摘要/Abstract

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、总氧化峰面积等参数可以得出Pt/SnO2/CNTs催化剂性能最佳。

关键词: 乙醇电氧化, 循环伏安法, 金属氧化物催化剂

Abstract: 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.

Key words: electrooxidation of ethanol, cyclic voltammetry, metal oxide catalyst
