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 electrocatalytic oxidation of several catalysts Pt / MO2 / CNTs (M = Sn, Ti, Ce) and Pt / CNTs in H2SO4 solution was studied by cyclic voltammetry. The results show that the addition of metal oxides is good for EtOH. Among them, Pt / CeO2 / CNTs exhibited significant oxidation performance for the ethanol electrooxidation intermediate product. The properties of Pt / SnO2 / CNTs catalysts such as Pt / SnO2 / CNTs optimal.
