Catalytic Oxidation of Methanol on Pt/C-SPE and PtRu/C-SPE Electodes

采用化学还原法制得直接甲醇燃料电池中甲醇阳极氧化的Ｐｔ／Ｃ和ＰｔＲｕ／Ｃ催化剂．结果表明后者比前者具有更高的催化活性．通过ＸＲＤ和ＸＰＳ的分析，阐明了Ｒｕ对提高甲醇电催化氧化活性的作用．Anode catalysts of methanol oxidation for direct methanol fuel cell, pt/C andPtRu/C,were prepared by chemical reduction in this work.The results indicated that the PtRu/Cshowed higher electrocatalytic activity than that of Pt/C. It was explained by XRD and XPS analysesthat the existence of Ru enhanced the catalytic activity for electrochemical oxidation of methanol.作者联系地址：中国科学院长春应用化学研究所Author's Address: Changchun Institute of Applied Chemistry,Chinese Academy of Sciences ,Changchun 13002
