Abstract

This invention relates generally to a method for producing fullerene nanotube catalyst supports and compositions thereof. In one embodiment, fullerene nanotubes or fullerene nanotube structures can be employed as the support material. A transition metal catalyst is added to the fullerene nanotubes. In a preferred embodiment, the catalyst metal cluster is deposited on the open nanotube end by a docking process that insures optimum location for the subsequent growth reaction. The metal atoms may be subjected to reductive conditions.
