摘　　要：应用循环伏安法研究了几种催化剂Pt/MO2/CNTs(M=Sn,Ti,Ce)和Pt/CNTs对乙醇在H2SO4溶液中的电催化氧化过程.结果表明,金属氧化物的加入有利于乙醇的电氧化.其中,Pt/CeO2/CNTs对乙醇电氧化中间态产物具有显著的氧化性能.综合初始氧化电位、峰电流和总氧化峰面积等参数,可以得出Pt/SnO2/CNTs催化剂性能最佳.The ethanol electrooxidation behaviors on Pt/MO2/CNTs（M=Sn,Ti,Ce）and Pt/CNTs catalysts in H2SO4 solutions were researched by cyclic voltammetry.It has revealed that the catalysts with the addition of metal oxides presented higher electrooxidation activity for ethanol,in particular,the Pt/CeO2/CNTs catalyst showed the best activity for ethanol electrooxidation intermediate.The Pt/SnO2/CNTs catalyst demonstrated the best ethanol electrooxidation activity when considering the synthetic effects of such parameters as the onset oxidation potential,peak current densities and total oxidation area.
