Carbon-supported PtAuSn nanoparticle catalyst was synthesized by intermittent microwave heating method. The catalyst thus obtained was characterized by transmission electron microscopy and X-ray diffraction analysis. The electrochemical performance of the catalyst, for the methanol oxidation reaction, was also investigated. The results indicate that the PtAuSn/C catalyst is uniformly dispersed on carbon and in the nano-size range. The electrochemical measurements indicate that PtAuSn/C nanoparticle catalyst synthesized by intermittent microwave heating method demonstrates a significantly higher electrochemically active area and higher catalytic activity than Pt/C for the methanol oxidation reaction.
