Paper Abstract

Eleven metals were laser-vaporized with carbon into Ar gas, and the growth of various nanocabon and composite materials were investigated. Controlling the Ar gas pressure and the metal content for Fe, Co, Ni, Cu, and Ag enabled the high yield (~70%) fabrication of single-wall carbon nanohorn particles including metal- or carbide-containing carbon nanocapsules. With the use of B, multi-wall carbon nanotubes were grown with a high yield of ~50%. For Al, Si, La, Y, and Gd, products such as carbide particles, polyhedra, and sea-urchin-type single-wall carbon nanotubes were formed. We will discuss the growth of these structures based on metal-catalyzed graphitization together with thermal graphitization.
