摘要：
Platinum nanoparticles supported on undoped nanodiamond (ND) with an average particle size of 50 nm were prepared using a microwave-heating polyol method. This method involves the addition of different amounts of chloroplatinic acid in the synthesis solution to obtain different Pt mass percentages. The Pt/ND catalysts were characterized by energy-dispersive spectroscopy, transmission electron microscopy, and X-ray diffraction. The small and uniform Pt nanoparticles were highly dispersed on ND supports. The mean size of the Pt particles was 4-5 nm. The effect of Pt loading on catalytic performance was investigated. Electrochemical measurements demonstrate that the Pt/ND catalysts prepared with proper Pt mass percentage exhibited a significantly high electrocatalytic activity for methanol electrooxidation.
