摘　　要：以含有多羟基的聚乙二醇为还原剂,采用水热还原技术一步法制备出Pt/石墨烯复合物电极材料。采用扫描电子显微镜(SEM)技术对石墨烯和Pt/石墨烯材料进行了形貌和结构表征。利用循环伏安电化学测试技术研究了该Pt/石墨烯电极对甲醇燃料小分子的电催化氧化性能。研究结果表明该复合材料作为阳极催化剂对甲醇表现出优异的电催化活性。该电极材料有望用作甲醇燃料电池的阳极催化剂材料。The Pt/graphene composite materials were synthesized via one-step hydrothermal reducing technique using polyethylene glycol（ PEG） as reductant. Scanning electron microscope（ SEM） was used to characterize the morphology and structure of graphene and platinum/graphene composite. Cyclic voltammetry was used to study the electrocatalytic activity of Pt/graphene electrode for methanol oxidation. Experimental results showed that serving as the anode catalyst,Pt/graphene had excellent electrocatalytic activity for methanol oxidation. The synthesis procedure was simple and green,and the prepared materials were expected to be used as an anode catalyst material of methanol fuel cells.
