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 electrode material was prepared by one-step hydrothermal reduction method using polyethylene glycol containing polyhydroxy as reducing agent. The morphology and structure of graphene and Pt / graphene were characterized by scanning electron microscopy (SEM). The electrocatalytic oxidation performance of the Pt / graphene electrode on methanol fuel small molecules was studied by cyclic voltammetry electrochemical test. The results show that the composite as the anode catalyst for methanol showed excellent electrocatalytic activity. This electrode material is expected to be used as an anode catalyst material for methanol fuel cells.
