摘要：

Carbon nanotubes and nanoparticles formed by dc arc-discharge evaporation of a carbon composite rod containing scandium oxide were studied by high-resolution scanning electron microscopy (SEM). Nanotubes obtained from the composite rod were more abundant than those obtained from pure carbon rod. Many fibrous nanotubes were gathered together and bunched to form long bundles. Moreover, a number of nanoparticles whose size was nearly the same as the diameter of nanotubes were attached to the surface of each tube in the bundle. It was found that scandium had the effect of promoting the growth of nanotubes.
