| 摘要： | Poly(butylene succinate) (PBS)-based nanocomposites, reinforced and toughened with ZnO-coated multi-walled carbon nano-tubes (MWCNT-ZnO), demonstrate signifcantly enhanced properties, making them ideal for potential applied in food packaging applications. This study explores the efects of varying proportions of MWCNT-ZnO on the overall characteristics
of these composites. The addition of 0.1 parts per hundred (phr) MWCNT-ZnO optimizes the nanocomposites mechanical properties, crystallinity, melting temperature, thermal stability, and barrier performance. Specifcally, the composite exhibits a 22% increase in tensile strength, a 28.4% rise in yield strength, and a remarkable 95.7% enhancement in the materials elongation at break, compared to the pure PBS matrix. Moreover, these nanocomposites exhibit excellent antibacterial properties, crucial for food preservation and safety. The soil burial test indicates that, except for the addition of 0.1phr which is lower than pure PBS, the biodegradation rate increases with the increasing addition of MWCNT-ZnO. This further suggests that a low nanoparticle fller content can enhance structural compactness, thereby improving the mechanical stability. The study also reveals notable preservation benefts for vegetables. When used for beef packaging, this composite material successfully extends the meats freshness period, substantially curtails bacterial proliferation, and ensures the beef remains within safe consumption parameters. The combination of enhanced mechanical, thermal, barrier, and antibacterial properties makes PBS/MWCNT-ZnO nanocomposites promising candidates for sustainable and efcient food packaging materials. |

| 摘要： | Conventionally, conductive additives and metallic current collectors are two major decisive factors to determine the electrochemical performances of electrode materials in supercapacitors (SCs). Without those, most reported materials for SCs are far beyond the standard performances. Herein, we develop a pore-size tunable and highly-pure nanosheet-like activated carbon (AC) from spent coffee grounds (SCGs) with high specific-surface-area (2497 m2 g-1) and large pore volume (1.28 cm3 g-1). The meso-pore/total-pore volume proportions (r) of the as-prepared samples, AC1200 (r10.25 %), AC1800 (r20.10 %), and AC2500 (67.34 %), are simply adjusted at desired temperatures (750-900 ℃) using physical activation with CO2. The SCG-based electrodes for symmetric electric double-layer capacitors (EDLC) were prepared using free-standing carbon films on cellulose separator, not on Al or Cu foils, without adding any conductive additives. Interestingly, the AC2500-based electrode, a narrow mesopore-rich (mainly 2-4 nm) AC, presents a superior capacitance of 222.4 F g-1 at 0.5 A g-1 in 1.5 M LiClO4/propylene carbonate. The capacitance is superior to those of micropore-rich samples (AC1200 and AC1800) including of two commercial products (YP-50 and ACS20). Furthermore, the AC2500-based EDLC exhibits a remarkable energy density of 48.3 Wh kg-1 at 627 W kg-1, and maintains a high energy density of 33.8 Wh kg-1 at 3733 W kg-1. In the present work, we demonstrate that narrow meso-pore (2-4 nm) dominant and nanosheet-like carbons would conduct high-performance electrochemical behaviors without the assistance of conductive additives. Moreover, we provide a promising preparation route for pore-size-tunable ACs from bio-mass wastes with remarkable performance for energy storage applications. |

| 摘要： | Activated carbon nanofibers with high specific surface area, excellent conductivity, and narrow pore-size distribution, is regarded as a promising electrode material for high-performance supercapacitors (SCs). Here, we report a facile route to synthesize large-scale amorphous carbon nanofibers (a-CF) using catalytic pyrolysis of acetylene (C2H2) at 260 ℃ over copper catalysts. The conversion rate of acetylene into a-CF is estimated as high as at 72.05 wt%. Subsequently, the as-prepared a-CF is transformed into activated carbon nanofibers (ACF) by KOH at 800 ℃ with high specific surface area and porous structures. Moreover, nitrogen-doped ACFs are conducted in the activation step through a physical mixing of a-CF/KOH/melamine with various ratios. For SCs, the as-prepared nitrogen-doped ACFs display excellent specific capacitance and cycle stability. In the three-electrode system, the N-doped ACF (CF-03) demonstrates a specific capacitance value of 227 F g-1 at 0.5 A g-1, and shows a 94% capacitance retention after a long cycle (10000 cycles) at 2 A g-1. Moreover, the CF-03-based two-electrode SC demonstrates a high energy-density of 14.30 Wh kg-1 and a high power-density of 79.88 W kg-1 in 1 M Na2SO4 electrolyte. In this work, we demonstrate a simple way to prepare large-scale a-CF, ACF, and N-doped ACFs, and also display their promising application in SCs. |

| 摘要： | In this study, we report a promising route to prepare pore-size tunable AC derived from waste coffee grounds (WCGs) using CO2 activation. The as-prepared AC with high purity and displays highest specific surface area of 2407 m2/g with a pore volume of 1.281 cm3/g. The pore size distribution is effectively tuned by adjusting the activation temperature during 800-950 °C, the volume portion rates of micropore/total-pore for AC can be tuned from 86.4 to 10.3 v/v %. For adsorption of dyes, methylene blue (MB) and methyl orange (MO), the adsorption capacities for MB (qe 678 mg/g), and for MO (qe 612 mg/g) are remarkably high comparing with that of a commercial AC (qe 181 mg/g). The kinetic adsorption results are well fitted with the pseudo-second order model and Langmuir isotherm. The high adsorption capacity of dyes onto AC can be attributed to a multi-interaction adsorption mechanism including of electrostatic interactions and π-π interactions. The present approach offers a facile route for conversion of biomass wastes towards a highly effective adsorbent for water remediation. |

| 摘要： | Nano-sized tin based compounds dispersed graphite composites, synthesized by the electroless plating process and pyrolysis method, act as efficient anode materials for lithium ion batteries (LIBs). The nano-sized tin complexes on the graphite surface can be obtained through a simple chemical reaction between Sn(BF4)2 and Na2S2O4 in aqueous solution and completely converted to SnO2 after pyrolysis. The synthesized tin-modified graphite composites were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and high-resolution transmission electron microscopy (HRTEM). The electrochemical performance of the composites for application as anode materials in lithium-ion batteries was investigated. The average particle size of nano-SnO2 is ~14.7 nm, as determined by HRTEM. Results of infrared spectra and electrochemical properties indicate that such an optimized nano Sn-based compound on graphite influences the formation of the thin solid electrolyte interface (SEI) in the electrode and thus improves the cycling performance, with high efficiency of 97.3% in LIBs. Nyquist plots show that during Li⁺ intercalation, the thin SEI film and the low charge transfer resistance of SnO2-modified graphite composite anode plays important roles in improving the electrochemical properties of LIBs. |

| 摘要： | One of the challenges for the non-oxidative coupling of methane (NOCM) is to effectively remove
the deposited coke over catalysts owing to the over-dehydrogenation of methane. Herein, we show that an insitu
growth of carbon nanotubes (CNTs) instead of coke were observed during NOCM over a CuSO4/γ-Al2O3
catalyst. The as-grown CNTs depict an unexpected promoting effect for NOCM with a highest activity of 0.48
mol kg cat-1·h-1, and maintained 85% activity after 200 h running time. The equilibrium methane conversion is
9.8% with a selectivity of 78.2% for C2 (C2H4 + C2H6) products. Highly dispersed Cu nanoparticles distributed on
the top of CNTs measured by transmission electron microscopy is proposed to result in high catalyst stability
during NOCM for 200 h instead of deactivation in several hours. Here, we firstly prove that the as-grown CNTs
can promote the catalytic activity of NOCM instead of deactivation by coking over catalysts. |

| 摘要： | A transformation of the industrial waste into porous materials for removing pollutants in water-treated systems is a promising route to reduce environmental impact on human life. Herein, a three-step treatment (thermal, chemical and activation) has been developed to effectively transform scrap tire carbons (STCs) into highly-pure activated carbons. Prior to activation, a purification process was conducted by thermal treating STCs at 800 oC under He gas, followed by a treatment at 500 oC under a mixture of He/H2. After that, the sample was refluxed in a diluted HCl solution at 100 oC for 4 h. This thermal and chemical process can reduce the ash content of the STCs from 12.54 to 1.46 wt% with a lower sulfur content (from 2.79 to 0.22 wt%). The activated carbon (AC) displays a specific surface area of 1048 m2/g (total pore volume of 1.16 cm3/g) with a yield of 21.4 wt%, prepared by treating the purified STCs at 900 oC for 4 h under a CO2 atmosphere. Without purifying treatments, the obtained AC shows lower specific surface area at 330 m2/g with a significant lower yield of 4.6 wt%. Highly-pure activated carbons (HP-AC) derived from purified STCs display a high adsorption capacity of 323 mg/g for methylene blue (MB). The adsorption kinetics of MB is suggested to follow the pseudo-second-order equation. The adsorption isotherm data depicts the Langmuir model. Electrostatic interaction between the oxygenated functional groups on HP-AC and MB is also discussed as the main driving force for the adsorption process. |

| 摘要： | Although studies on carbon nanotube (CNT) growth have made great advancements, direct growth of highly dense CNTs on desired substrates or positions remains an important challenge. Herein, we report a simple method to directly fabricate a CNT forest on a quartz surface using a copper catalyst at 850oC under a stream of argon-diluted ethanol. Copper nanoparticles (NPs) are used as catalysts, which are generated through flow-vapor-deposition of copper (II) acetylacetonate on a thermal-treated SiO2 (quartz) or Si (silicon wafer) surface. Dense tangled CNT forms on the quartz surface. However, when a silicon wafer is used as the substrate, the only product is a carbon-covered copper NPs instead of CNTs. The growth yield of CNTs is approximately 10.5 g CNT/g Cuh as characterized by thermogravimetric analysis, which is remarkably high compared with those achieved by conventional copper-based catalysts. The stronger metal-support interaction of copper NPs with quartz is suggested to be the key factor for CNT growth. Bamboo-like MWCNTs (BMWCNTs) are the main structures formed through transportation of copper NPs during CNT formation as evidenced by HR-TEM micrographs. Moreover, CNT-grown quartz has superhydrophobic features with a contact angle of 154o, revealing its promising application in self-cleaning coatings. |

| 摘要： | Transformation of industrial waste carbon-based materials and biomass are attracted greatly
interest in academia and industrial owing to several potential applications. These also depict
promising routes for resolving environmental impact from the above-mentioned wasted materials.
Physical or chemical activations are usually employed for transforming scrap tire and biomass
into activated carbons (AC) with high specific surface area and porous structures. The former is
proceeded by steam or carbon dioxide; the latter is completed with several chemicals, e.g. KOH,
H3PO4, NaOH, etc. Here, we systematically introduce recent advancements of AC derived from
scrap tire and agricultural biomass and their applications in dye adsorption, supercapacitors, and
heavy metal removers. These studies not only give new concepts for looking new precursors of
AC, but also provide promising ways to save our planet in reducing environmental wastes. |

| 摘要： | In this work, we have developed an one-step process for synthesizing carboxylic-functionalized carbon nanofibers (CNFs)-encapsulated Ni magnetic nanoparticles (Ni@CNFs) that exhibit an excellent magnetic response and a large content of hydrophilic carboxylate groups with a negative charge (RCOO-) on the carbon surface. The carbon-encapsulated magnetic Ni nanoparticles could be rapidly separated from water, and they showed high efficiency for adsorption of the antibiotic sulfamethoxazole (SMX) in aqueous solution. The adsorption of SMX on Ni@CNFs as a function of pH was investigated, and the greatest adsorption occurred at pH 7.0. The adsorption isotherms for SMX on Ni@CNFs depended on different pH values. A Monte Carlo simulation was used to probe the relationship between molecular conformation and π-π interaction. The high adsorption of SMX on Ni@CNFs at pH 7.0 could be ascribed to deprotonated SMX being easily converted to a planar-like conformation, thereby resulting in the formation of π rings that were approximately parallel to the graphite surface and that enhanced strong π-π interaction. Electrostatic and π-π interactions both contributed to deprotonated SMX adsorption at pH 7.0 and 5.6, and they influenced the adsorption isotherm toward the Freundlich model. However, in weakly acidic environments (pH 2.0 and 4.0), the electrostatic interaction alone could induce an adsorption pattern that was similar to the Langmuir model. |

| 摘要： | An one-step process for the synthesis of hydrophilic carbon nanofibers (CNFs) through CO2 hydrogenation on Ni-Na/Al2O3 was developed for the loading and targeted delivery of the anticancer drug doxorubicin (DOX). CNFs that were synthesized on Ni-Na/Al2O3 for 9 h at 500°C exhibited an adequate magnetic response and a large content of hydrophilic oxygen-containing functional groups on the carbon surface, resulting in excellent colloidal solution. The CNFs material exhibited a highly efficient capacity for DOX adsorption, particularly at pH 9.0. The loading and release of DOX was strongly pH dependent, possibly due to electrostatic and π - π stacking interactions between DOX and CNFs sample. The Langmuir isotherm and pseudo second-order kinetics of DOX- loaded CNFs were well-modeled for the process of DOX adsorption. DOX-loaded CNFs targeted cancer cells more selectively and effectively than free DOX and exhibited a marked tendency to kill HeLa cancer cells and reduced toxicity to normal human primary fibroblast (HPF) cells. |

| 摘要： | A method is developed for growing three-dimensional hierarchic structures of porous
graphenic carbon film/hollow carbon nanorods where porous graphenic carbon film is first
synthesized followed by, growth of carbon nanorods. By annealing an amorphous carbon
layer deposited underneath a nickel thin film at elevated temperatures, the porous graphenic
carbon film forms on top via carbon diffusion and precipitation from the grain boundaries
of the nickel film. The porosity of the graphenic carbon film is determined by the
surface voids of the nickel film resulting from grain coalescence during annealing. Hollow
carbon nanorods can then be grown on the pore edges of the porous graphenic carbon film
by chemical vapor deposition without catalysts. It is speculated that the dangling bonds of
the carbon atoms on the pore edges of the graphene layers might be responsible for the
nucleation of the hollow carbon nanorods. The microstructures and growth mechanisms
of both porous graphenic carbon film and hollow carbon nanorods are characterized and
discussed in detail. |

| 摘要： | Catalytic CO2 hydrogenation has been studied on both 0.5 wt% and 10 wt% Ni/SiO2 catalysts with
particular focus on the production of CO and CH4. The large difference in Ni particle size between the 0.5
wt% and 10 wt% Ni loadings strongly affects the kinetic parameters of CO2 hydrogenation, the formation
pathways of CO and CH4, and the reaction selectivity. The consecutive and parallel reaction pathways
show preferences for small Ni clusters and large Ni particles, respectively. At low Ni loading (0.5 wt%), the
catalyst shows a comparatively higher catalytic activity for CO2 hydrogenation with high CO selectivity.
With Ni loading increased to 10 wt% (ca. 9 nm particles), the selectivity is switched to favor CH4 formation.
A formate species in a monodentate configuration is intricately involved in CO2 hydrogenation on both Ni/
SiO2 catalysts, regardless of the Ni loading and particle size. The consecutive pathway, which is favored on
small Ni particles, is attributed to low H2 coverage on the Ni surface, leading to dissociation of formate
intermediates resulting in CO formation and high CO selectivity. The reaction of CO2 hydrogenation on
large Ni particles may be controlled by mixed consecutive and parallel pathways, providing the likelihood
that the formate intermediate is competitively hydrogenated to CO or CH4 as part of a parallel reaction
pathway. The sites corresponding to kink, corner or step positions on the Ni/SiO2 surface are proposed as
the primary active sites for CO2 hydrogenation. |

| 摘要： | Metal-catalyst-free growth of carbon nanostructures, e.g. carbon nanotubes (CNTs) or carbon nanofibers (CNFs), on typical materials is a promising route to achieve further applications without interference of unwanted metal catalysts. Here, we report that carbon black (CB) can act as catalysts to controllably grow CNTs or CNFs yielding a bi-functional hybrid structure-CNTs/CB or CNFs/CB through a metal-catalyst-free chemical vapour deposition (MCF-CVD) in a reaction temperature range of 800-950 oC. We find that the decomposition steps of carbon source is a crucial factor to determine the formation of CNTs (ethylene), CNFs (acetylene) or amorphous carbons (ethanol and cyclohexane) evidenced by the gas-composition analysis. The growth yields of CNTs or CNFs catalysed by various CBs display a linear corresponding with the surface areas of CBs, indicating that structural morphologies of CB dominate the growth of carbon nanostructures. The formation of CNTs/CB or CNFs/CB is proposed to obey the vapour-solid-surface-solid model with an activation energy of 59.0 kJ/mol. The growth mechanism of CNTs/CB or CNFs/CB is suggested that a direct dehydrogenation route of carbon sources (ethylene and acetylene) would occur on CB surfaces through self-assembling. The multi-step decomposition route of carbon sources (ethanol and cyclohexane) would generate amorphous carbons only. These findings open a new route to prepare unique carbon structures through a metal-catalyst-free CVD. |

| 摘要： | A growth of bamboo-like multi-walled carbon nanotubes (CNTs) without the formation of amorphous carbons (a-C) have been developed using copper-based catalysts by catalytic chemical vapor deposition (CVD) with diluted ethylene at 700-900 oC. The as-grown CNT soot was characterized by transmission electron microscopy, thermogravimetric analysis and Raman spectra. Weak metal-support interaction of sulfated-assisted copper catalyst (CuSO4/SiO2) can give a high-purity growth with remarkable yields of CNTs (2.24-6.10 CNT/g Cuh) at 850-900 oC. Additionally, hydrogen-assisted CVD can activate inert copper catalysts, e.g. Cu(NO3)2/SiO2 or Cu(CH3COO)2/SiO2, towards the growth of CNTs. |

| 摘要： | The well-controlled growth of carbon nanotubes (CNTs) at low temperature ( 1073K ) using non-iron group metal catalysts remains a challenge. Here, we report that CNTs can be grown at 773-1173 K over an atomic layer epitaxy (ALE) prepared copper catalyst (ALE-Cu/SiO2) using chemical vapour deposition in helium diluted ethylene. At the same reaction conditions, only amorphous carbon can be generated 10 over an impregnation (IM) method prepared copper catalyst (IM-Cu/SiO2). A metal-support interaction (MSI) model is proposed to describe the interaction between the ALE prepared Cu nanoparticles (NPs) and SiO2 support through the results of temperature programmed reduction profiles, x-ray photoelectron spectra and in situ x-ray diffraction (XRD) patterns. Structurally stabilised Cu NPs in ALE-Cu/SiO2 catalyst indicate that the strong MSI site of Cu NPs and/or copper silicide(Cu3Si) evidenced by in situ 15 XRD patterns would be the active centers to fabricate CNTs. Our observations provide new insights into controlling the CNT growth at low-temperatures over non-ferromagnetic catalysts. |

| 摘要： | A sulfate-activated effect is developed to describe the growth of bamboo-like carbon nanotubes (CNTs) over copper catalysts using chemical vapor deposition with helium diluted ethylene. Sulfate-assisted copper catalysts can afford a high-yield growth of bamboo-like CNTs at mild temperature- 800 oC, however, non-sulfate assisted copper catalysts, e.g. copper acetate and copper nitrate prepared catalysts, were inert for the CNT growth and only obtained amorphous carbons (a-C) surrounding around copper nanoparticles at the same conditions. Nevertheless, the addition of sulfate ion in the preparation step for the two inert catalysts can activate their abilities for the CNT growth with remarkable yields. Further Raman spectra analysis demonstrates a linear dependence between the concentration of sulfate ions in copper catalysts and the ratio of CNT/a-C in the as-grown carbon soot. The sulfate-activated effect for the CNT growth over copper catalysts would relate to a three-way interaction of sulfate ions, copper nanoparticles and support. In situ TEM images for an as-grown CNT irradiated by electron beams without the inlet of carbon sources reveal an unaware pathway of carbon diffusion through the bulk of copper nanoparticles and enlarge the inner-wall thickness of the on-site CNT. This carbon diffusion model over sulfate-assisted copper catalysts can give new insights to explain the CNT growth mechanism over non-magnetic metal catalysts. |

| 摘要： | Commercially available Ni/Al2O3 samples containing various concentrations of potassium were used to achieve
carbon deposition from CO2 via catalytic hydrogenation. Experimental results show that K additives can
induce the formation of carbon nanofibers or carbon deposition on Ni/Al2O3 during the reverse water-gas
shift reaction. This work proposes that the formation rate of carbon deposition depends closely on ensemble
control, suggesting that the ensemble size necessary to form carbon may be ?0.5 potassium atoms. The
results of CO2 temperature-programmed desorption provide strong evidence that the new adsorption sites for
CO2 created on Ni-K/Al2O3 closely depend upon the synthesis of carbon nanofibers. It is found that some
potassium-related active phases obtained by calcination and reduction pretreatments can participate in the
carbon deposition reaction. The formation pathway for carbon deposition suggests that the main source of
carbon deposition is CO2 and that the pathway is independent of the reaction products CO and CH4 in the
reverse water-gas shift reaction. |

| 摘要： | We report on the observation of self-assembled carbon nanostructures on a standard transmission electron microscopy (TEM) Au substrate formed via thermal chemical vapor deposition. Multi-walled carbon nanotubes (MWNTs) and other carbon nanostructures (CNs), such as carbon nanofibers and carbon nanoparticles (NPs), could be fabricated through structural transformation of meta-stable carbon layers on the Au surface during 800-850oC with the thermal decomposition of ethylene. At these temperatures, we found that Au NPs will form immediately through the structural transformation of the Au grid surface in helium atmosphere. The Au NPs work as active centers to trigger the decomposition of ethylene into carbon atoms, which spillover to form meta-stable carbon layers or amorphous carbon nanobugs and then to form as CNs via self-assembling. The growth of CNs was characterized by field-emission scanning electron microscopy (SEM), high-resolution TEM and RAMAN spectroscopy. The transformation of amorphous carbon nanobugs by electron beam irradiation is also recorded by in-situ monitoring of TEM. |

| 摘要： | Synthesis of carbon nanotubes (CNTs) by catalyst-free chemical vapor deposition (CFCVD)
is one of the most important challenges in nanotube science. Self-assembling multi-walled
CNTs (MWCNTs) were produced on a porous carbon surface using carbon black (CB) as a
substrate, at 800 C by the decomposition of diluted ethylene. MWCNTs with an outerdiameter
distribution of 20–80 nm, examined by scanning and transmission electron
microscopy, could be self-assembled on pore structures of CB surface by CFCVD. |

| 摘要： | Despite the fact that porous carbons are the primary components of electric double-layer capacitors (EDLC), conductive additives have typically been necessary to aid in the establishment of improved conductive pathways. In this study, we use two-dimensional porous carbon sheets (2D PCNs) derived from spent coffee grounds as the active component and integrated them with two structurally complementary carbon blacks (CB)-BP2000 and Super P to compose a highly stable EDLC electrode in an organic electrolyte. The carbon electrode with the best mass ratio is AC2500/BP2000/Super P 100/15/5 (AC25-BP75SP25) and was prepared using a suction-fltration method on a cellulose separator rather than direct coating on a metallic foil. The specifc capacitance of AC25-BP75SP25-based EDLCs in 1 M TEABF4/propylene carbonate is as high as 226.8 F g−1 at 0.5 A g−1. Furthermore, the cycling tests show a specifc capacitance of 194.6 F g−1 at 5 A g−1 with a high-voltage window of 2.5−2.7 V and a Coulombic efciency near 98 % after 50,000 cycles. The value is remarkably stable when compared with the AC2500-based electrode without conductive CB or adding only one kind of CB. The energy density can reach a high level of 56.7 Wh kg−1 @ 750 W kg−1 and 42.8 Wh kg−1 @ 11.8 kW kg−1, indicating that the assembled EDLC can maintain a high energy density when operated under harsh charge−discharge conditions. Our fndings could provide a new strategy to practically utilize carbon-electrode materials derived from biomass wastes for high-performance EDLC. |

| 摘要： | Although the weight ratio of electron conductive additives and the binder to porous
carbons in the electrode component of electric double-layer capacitors (EDLC) is
minimal, however, without them the electrochemical performances of EDLC would
decay quickly. In this work, we present a one-step approach for manufacturing a
unique conductive carbon material that shows highly connecting hollow structures as
well as approximate oxygenated surface groups to create a synergy effect with
aqueous binder and the main component, porous carbon. The as-prepared carbon
nanospheres (HCNs) were generated from a typical carbon black-PC20 in air (denoted
as PC20HT) at mild temperatures ranging from 400 to 700 °C for 2-4 h at a massive
scale of approximate 1 kg h-1. The as-prepared PC20HT displays a high specific
surface area of 657 m2 g-1 (the pristine PC20 has 112 m2 g-1) with a pore volume of
0.71 cm3 g-1, and an oxygen content of 14.10 wt%. Interestingly, a premixing of
PC20HT and porous carbon is required before making the electrode pastes. The well
premixed carbon materials and a water-soluble binder-polyacrylic acid are composed
into highly-stable components as EDLC electrodes in an organic electrolyte. As
consequently, the PC20HT-assisted electrodes demonstrate highly stable life cycles
(charge-discharge behaviors), with a retention rate 82.13 % over 50,000 cycles at a
narrow voltage window of 2.5-2.7 V at 0.5 A g-1 when compared to two conventional
conductive carbons, BP2000 (68.45 %) and Super P (67.46%). Thermal annealing at
900 ℃ in Ar reduces the oxygen content of PC20HT to 4.25 wt% (referred to as
TPC20HT), increasing the retention rate of life cycle to 88.89 % after the same cycles.
TPC20HT-assisted EDLC electrodes exhibit a superior energy density of 34.76 Wh kg
1, which is higher than CB-BP2000 and Super P-assisted EDLC electrodes. The
transforming of structural morphologies as well as the surface oxygenated and
graphitic structures of the as-prepared HCS, PC20HT, and TPC20HT were also
described before and after long-term cycling. This simple route for producing
conductive carbons is applicable in an aqueous binder system for preparing EDLC
electrodes with a cost-effective and environmentally friendly approach. |

yield strengths being achieved at a 3% CFG concentration. Relative to pure PVA, the tensile strength
and yield strength of the composite increased by 2.07 and 2.01 times, respectively. XRD analysis
showed distinct changes in the crystalline structure of PVA with the addition of CFG, highlighting the
influence of CFG on the composite structure. FTIR and XPS analyses confirmed the formation of ester
bonds between CFG and PVA, enhancing the overall performance of the material. TGA results also
demonstrated that the presence of CFG enhanced the thermal stability of CFG/PVA nanocomposite
f
ilms. However, analyses using scanning electron microscopy and transmission electron microscopy
revealed that a 3% concentration of CFG was uniformly dispersed, whereas a 6% concentration of
CFGcaused aggregation of the nanofiller, leading to a decrease in performance. The incorporation
of CFGsignificantly enhanced the water vapor and oxygen barrier properties of PVA, with the best
performance observed at a 3% CFG concentration. Beyond this concentration, barrier properties were
diminished owing to CFG aggregation. The study further demonstrated an increase in electrical
conductivity and hydrophobicity of the nanocomposites with the addition of CFG. Antibacterial tests
against E. coli showed that CFG/PVA nanocomposites exhibited excellent antibacterial properties,
especially at higher CFG concentrations. These findings indicate that CFG/PVA nanocomposites,
with an optimized CFG concentration, have significant potential for applications requiring enhanced
mechanical strength, barrier properties, and antibacterial capabilities. |

| 摘要： | Surface-passivation is an effective way to allow the anode materials can deliver long-term superior electrochemical performance for lithium-ion batteries (LIBs). Herein, we develop a simple solution suspension-coating method to prepare thickness-controllable nano-carbon layer (NCL) on a synthesis graphite-mesocarbon microbeads (MCMB) using aqueous glucose solutions with a surfactant-triton X-100 at 25 ℃. This simple process can control the thickness of the NCL on MCMB with a range of 1.5-20 nm with various glucose concentrations. The as-formed NCL can reduce the defect sites on MCMB surface and create slightly porous structures within NCL. For electrochemical performance in LIB, we observed that the carbon-coating thickness at around 4 nm shows better reversible capacity (from 295 to 347 mAh g-1), lower Li+ diffusion resistance, stable cycle-life, and superior C-rate performance. As our results, we provide a simple method to stabilize surface properties of MCMB and show better electrochemical performance in LIB. Moreover, this method can be easily exploited in the industrial with a massive production. |

| 摘要： | The mechanical properties and wear resistance of carbon black/natural rubber (CB/NR) composites are significantly influenced by the dispersion degree of CB in rubber. Here, we present a novel reinforcement theory using atomic force micros-copy (AFM) to quantify the adhesive thickness of rubber molecules around the CB particles as well as the height, area, and volume in NR. The thickness of the bonded rubber (BR) was found to vary between 3 to 7 nm depending on the values of the specific surface area (NSA) for CB. This indicates that higher BR content owing to higher NSA of CB with a smaller particle size showing higher active po-sitions to anchor rubber molecules. Nanoindentation of AFM was used to de-termine the surface hardness of CB in NR, the value will decrease with the in-creasing of the BR height. In this study, we demonstrate a well reinforcement mechanism of CB in NR with the factor of BR, surface hardness, 100%/300% modulus, and tensile strength. |

| 摘要： | The photon energy-dependent selectivity of photocatalytic CO2-to-CO conversion by CsPbBr3 nanocrystals (NCs) and CsPbBr3/g-C3N4 nanoheterostructures (NHSs) was demonstrated for the first time. The surficial capping ligands of CsPbBr3 NCs would adsorb CO2, resulting in the carboxyl intermediate to process the CO2-to-CO conversion via carbene pathways. The type-II energy band structure at the heterojunction of CsPbBr3/g-C3N4 NHSs would separate the charge carriers, promoting the enhancement in the efficiency of CO2-to-CO conversion. The electron consumption rate of CO2-to-CO conversion for CsPbBr3/g-C3N4 NHSs was found to intensively depend on the rate constant of interfacial hole transfer from CsPbBr3 to g-C3N4. An in situ transient absorption spectroscopy investigation revealed that the half-life time of photoexcited electrons in optimized CsPbBr3/g-C3N4 NHS was extended two times more than that in the CsPbBr3 NCs to improve the efficiency in the CO2-to-CO conversion. The current work presents important and novel insights of semiconductor NHSs for solar energy-driven CO2 conversion. |

| 摘要： | Although SnO2 nanoparticles (NPs) as the anode material can deliver high specific capacity for sodium-ion batteries (SIBs), however, their electrochemical performances will decay quickly owing to the aggregation of SnO2 NPs during charge-discharge cycles. Herein, we report a simple hydrothermal method to prepare SnO2 NPs decorated on highly structurally-connected carbon nanospheres (HS-CCN) with or without nitrogen doping. As an anode for SIBs, SnO2/N-HS-CCN delivered a good reversible capacity of 294 mAh g-1 after 150 cycles at 0.1 A g-1. This is remarkably high when compared with previous reports. In addition, the integration of synergistic effect between SnO2 and N-HS-CCN can exhibit superior electrochemical behaviors than that of HS-CCN without N-doping, non-dispersed SnO2, or pure N-HS-CCN. This work highlights that nitrogen-doped carbon materials can effectively bridge the nano-SnO2 particles with high electron mobility, thus offering high capacity in SIBs from low to medium-high current densities. |

| 摘要： | Highly structural-connecting carbon nanospheres (CNSs) are prepared using thermal pyrolysis of acetylene at 580 ℃ with a yield of 1 kg h-1. The as-prepared CNSs present a particle-size distribution in a range of 60-90 nm, and display a highly-connected structure (the specific oil-adsorption value is 180 mL/100g according to the ASTM D2415-19 method) with a specific surface area of 30 m2 g-1. The as-prepared CNSs were treated with an acid purification (1M HNO3 80℃ for 2 h) or thermal treatments at higher temperatures (800 or 1000 ℃ for 2 h) under argon atmosphere. The CNSs-based samples demonstrate admirably electrochemical performance as the anode materials for lithium-ion batteries (LIBs). Additionally, HNO3-treated CNSs display better performances in LIBs comparing with pristine, thermal-treated CNSs, graphite, and carbon black-super-P and acetylene black. For the HNO3-CNSs sample, the first charge-discharge cycle of the specific charge capacity is 506 mAh g-1, and which maintains at 420 mAh g-1 of specific discharge capacity, the initial coulombic efficiency is 85.0%. Moreover, the rate capacity is conducted at various current densities from 0.05 to 2 A g-1, the capacitance retention rate can maintain above 98 % after 100 cycles. Remarkably, the HNO3-treated CNSs exists excellent rate capacity of 280 mAh g-1 at 2 A g-1, which is superior to those of previously reported CNSs. Herein, we provide a facile route to massively prepare a high-performance anode material for LIBs. |

| 摘要： | Since 1991 discovered by S. Iijima, carbon nanotubes-CNTs have been studied more than 27 years. The detailed description of CNTs from fundamental researches to industrial applications have been discussed more than ten-thousand articles. Generally, vapor-liquid-solid (VLS) is a typical model to reveal the growth mechanism of CNTs, especially, while the iron-group metals were used as the catalysts. However, from 2006, several researchers found non-iron group metals, e.g. Cu, Ag, Au, and Pt, can grow CNTs as well as the non-metal elements, e.g. carbon black, diamond, and silicon. Recently, a new surface diffusion model for CNT growth have been wildly accepted using non-iron group elements. Here, we review several reports for the growth of CNTs over copper catalysts, and hope to provide new insights for CNT growth mechanism. |
