Low-temperature synthesis of high-purity single-walled carbon nanotubes from alcohol
By using alcohol as the carbon source, a new simple catalytic chemical vapor deposition technique to synthesize high-purity single-walled carbon nanotubes at low temperature is demonstrated. Because of the etching effect of decomposed OH radical attacking carbon atoms with a dangling bond, impurities such as amorphous carbon, multi-walled carbon nanotubes, metal particles and carbon nanoparticl...
متن کاملNew Ccvd Generation and Characterization of Single-walled Carbon Nanotubes
Bulk amount of single-walled carbon nanotubes (SWNTs) have been generated by laser-oven or arc-discharge techniques, and recently by catalytic chemical vapor deposition (CCVD) technique. CCVD technique is being intensively developed for the possibility of larger-scale production of high quality SWNTs at a low cost. We have demonstrated the high-quality generation of SWNTs by utilizing gas phase...
متن کاملGeneration of single-walled carbon nanotubes from alcohol and generation mechanism by molecular dynamics simulations.
Recent advances in high-purity and high-yield catalytic chemical vapor deposition (CVD) generation of single-walled carbon nanotubes (SWNTs) from alcohol are comprehensively presented and discussed on the basis of results obtained from both experimental and numerical investigations. We have uniquely adopted alcohol as a carbon feedstock, and this has resulted in high-quality, low-temperature sy...
متن کاملMolecular dynamics simulation of formation process of single-walled carbon nanotubes by CCVD method
Formation process of single-walled carbon nanotubes by the catalytic chemical vapor deposition method is studied by molecular dynamics simulation. We start the calculation with randomly distributed carbon-source molecules and a nickel cluster to investigate the metal-catalyzed growth of a cap-structure of a nanotube. When the catalytic cluster reaches saturation with carbon atoms, hexagonal net...
متن کاملGram-scale CCVD synthesis of double-walled carbon nanotubes.
Synthesis of clean double-walled carbon nanotubes by a catalytic chemical vapour deposition (CCVD) method is reported; the catalyst is a Mg(1 - x)Co(x)O solid solution containing additions of Mo oxide; this MgO-based catalyst can be easily removed, leading to gram-scale amounts of clean carbon nanotubes, 77% of which are double-walled carbon nanotubes.
