Effects of Microwave-synthesizing Parameters on Structure and Electro-catalytic Activity of Pt_2Mo/C towards Methanol Oxidation

Pt2Mo/C was prepared by microwave-synthesis to improve the catalytic performance of Pt-based catalysts towards methanol oxidation.Effects of reaction and sonicating time on the crystal structure,micro-morphology and electro-catalytic activity of Pt2Mo/C were systematically investigated.The results show that the crystal structure of Pt2Mo/C is mainly determined by the reaction time while the sonicating time has little influence on it.The micro-morphology of Pt2Mo/C is determined by both the reaction and sonicating time.The influencing sequences of reaction and sonicating time on electro-catalytic activity of Pt2Mo/C are 10min15min20min 5min and 60min100min30min0min,respectively.The optimized parameters of preparing Pt2Mo/C owing best catalytic activity towards methanol electro-oxidation are 10min of reaction time and 60min of sonicating time.
