Аннотация: Density functional theory calculations in a basis of plane waves were preformed to determine diffusion process characteristics for atomic hydrogen chemically adsorbed on the surface of (5,5), (8,8) and (8,0) single-walled carbon nanotubes. It has been determined that carbon nanotubes can be used for the storage hydrogen in a chemicПоказать полностьюally bound atomic state. The saturation process of carbon nanotubes with hydrogen should be carried out at high temperatures and in the presence of catalyst that would decompose hydrogen into atomic form. High temperatures aid the diffusion process leading to uniform distribution of hydrogen atoms on carbon nanotube surface. At standard temperatures the migration of hydrogen atom on the nanotube surface is hindered significantly. Copyright © 2007 BioChem Press.
