Abstract

A facile, rapid and green method based on potentiostatic electrodeposition is developed to synthesize a novel H3PMo12O40-Pt/reduced graphene oxide (denoted as PMo12-Pt/rGO) composite. The as-prepared PMo12-Pt/rGO is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The results reveal that graphene oxide (GO) is reduced to the rGO by electrochemical method and POMs clusters are successfully located on the rGO as the modifier. Furthermore, the PMo12-Pt/rGO composite shows higher electrocatalytic activity, better tolerance towards CO and better stability than the conventional pure Pt catalyst. View Full-Text
