Growth of metal-catalyst-free nitrogen-doped metallic single-wall carbon nanotubes.
Nitrogen-doped (N-doped) single-wall carbon nanotubes (SWCNTs) were synthesized by chemical vapor deposition using SiOx nanoparticles as a catalyst and ethylenediamine as the source of both carbon and nitrogen. The N-doped SWCNTs have a mean diameter of 1.1 nm and a narrow diameter range, with 92% of them having diameters from 0.7 to 1.4 nm. Multi-wavelength laser Raman spectra and temperature-...
متن کاملBoosting electrical conductivity in a gel-derived material by nanostructuring with trace carbon nanotubes.
An organogelator with two distinct π-functional units is able to incorporate carbon nanotubes into its mesh of fibres in the gel state. The morphology of the material derived from this nanocomposite after evaporation of the solvent is a complex mesh of fibres which is clearly different from the pure gelator. This feature indicates a role of the nanotubes in assisting the formation of a fibre st...
متن کاملA Theoretical Study of H2S and CO2 Interaction with the Single-Walled Nitrogen Doped Carbon Nanotubes
The physical adsorption of hydrogen sulfide and carbon dioxide gases on the zigzag (5,0) carbon nanotubes doped with nitrogen was investigated through the application of B3LYP/6-31G* at the level of theory on Gaussian 03 software. A variety of stable and high abundance structures of nitrogen doped carbon nanotubes were considered in order to study the interaction between the mentioned gases in ...

متن کاملIodine doped carbon nanotube cables exceeding specific electrical conductivity of metals
Creating highly electrically conducting cables from macroscopic aggregates of carbon nanotubes, to replace metallic wires, is still a dream. Here we report the fabrication of iodine-doped, double-walled nanotube cables having electrical resistivity reaching ∼10⁻⁷ Ω.m. Due to the low density, their specific conductivity (conductivity/weight) is higher than copper and aluminum and is only just be...
