Abstract
Behaviors of carbon nanotubes (CNTs) in H-2 atmosphere or CH4 + H-2 mixture s, transforming mechanism of CNTs to diamond embryo were investigated. Expe rimental results show that CNTs could be etched by H-2 and transformed to c arbon nanoparticles under conditions of hot-filament chemical vapor deposit ion. The mechanism can be concluded that CNTs were broken down by H-2, tran sformed to carbon nanoparticles or shorter CNTs; on surface of carbon nanop articles or end caps of CNTs diamond crystals were nucleated and grown up.
