CATALYST FOR CATALYZING GROWTH OF SINGLE-WALL CARBON NANOTUBES

摘要

Chemical vapor deposition (CVD) is used to synthesize single-wall carbon nanotubes by a catalytic reaction, and a method of preparing the catalyst is also provided. A transition metal catalyzing growth of carbon nanotubes, an oxide of a precursor metal preventing agglomeration of catalyst particles, and a precious metal are essentially consisted in the catalyst. The catalyst particles can be further dispersed by quasi-explosive effect occurred when the oxidized precious metal is reduced.
