摘　　要：为进一步提高催化剂(Ag,Pd和Pt)对氧还原反应(ORR)的催化活性,通过原位还原法将催化剂选择性沉积在碳纳米管(CNTs)负载的SnO2表面,制得相应复合催化剂,同时制备了将SnO2溶解处理的催化剂以作比较.电化学测试结果显示,SnO2可显著改善贵金属催化剂ORR催化活性,表明利用SnO2提高表面负载金属催化剂ORR活性有普适意义.To further improve the catalytic activity of metal catalysts (Ag,Pd and Pt) for Oxygen Reduction Reaction (ORR), in-situ reduction strategy was employed to selectively depositing catalysts on SnO2 supported by carbon nanotubes (CNTs). Corresponding catalysts for comparison were also prepared by dissolving SnO 2 from the above mentioned catalysts. Electrochemical characterization showed that SnO2 can evidently improve the ORR activity of metal catalysts (Ag, Pd and Pt), indicating that introducing SnO2 is of great significance for improving the ORR activity of SnO2-supported metal catalysts.
