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.

年度2012
類別期刊論文
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 Cuh) 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.

類別期刊論文
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We report a method to significantly remove impurities and further activated intoactivated carbons from the scrap tire carbons (STCs) using thermal and chemical treatments.The pristine sample was thermal treated at 800 oC in He (gas flow 45 sccm) for 2 hours andfollowed a treatment at 500 oC with a mixture of He/H2 (1/3 60 sccm) for 2 hours. After thethermal treatments, the sample was refluxed in a diluted acid solution (HCl 2.0 M) for 4 hours at100 oC. This thermochemical process can reduce the ash content of the STCs from 12.54 to 1.46wt% with a specific surface area increasing from 42 to 96 m2/g, the carbon purity is as high as98.14 % and the sulfur level of the treated STCs is lowering down to 0.22wt%. Further treatedthe purified STCs using CO2 at 900 oC can generate activated carbons with a high specificsurface area at 1048 m2/g, the yield is approximately at 22.4 wt%. Our study can provide newinsights for recycling wasted tires carbons into highly pure activated carbons.

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.
