Carbon nanotube and filament could be obtained by the decomposition of C2H4 using oxidized diamond-supported metal catalysts with three distinct structural types. Oxidized diamond is proposed as a novel catalytic means for the synthesis of nanocarbons. Oxidized diamond may catalyze unique reactions of importance in carbon nanotube and filament synthesis.

In this study, we synthesized carbon nanofilament on ethylene decomposition from it was using oxidized diamond-supported for Ni catalyst. Precious supported metals were used for synthesized of carbon nanofilament and preparation of electrocatalyst by using for methanol oxidation reaction. The electrocatalytic activity of Pt-loaded catalysts were examined by Cyclic voltammetry (CV) measurement. The result of CV measurement, Pt-loaded synthesized CNF was a high catalytic activity than carbon black (Vulcan® XC-72) and multi walls carbon nanotube (MWCNT).
