摘要
使用溶胶凝胶法制备了具有电催化活性的Pt-SnO2／C催化剂，并采用XRD、场透射电子显微镜及电化学测试手段对其进行表征。XRD及场发射透射电子显微镜的结果显示所制得的催化剂平均粒径约为4～20nm。采用循环伏安，交流阻抗的测试手段测试了其在乙醇体系中的电催化活性。该催化剂在乙醇电氧化过程中具有很好的稳定性和较高的电催化活性，其电催化活性高于Pt／C。
In this paper, a series of complex catalysts of Pt-SnO2/C were prepared using sol-gel method and the preparation process was optimized. XRD, FETEM and the electrochemical measurements were used to characterize the prepared catalysts. The results of XRD and FETEM indicated the average size of the catalyst particles was 4 nm-20 nm. CV and EIS were used to test the electrocatalytic activity in the solution of ethanol. These catalysts possess high stability and electrocatalytic activity during the electrooxidation of ethanol, and the electrocatalytic activity was higher than that of Pt/C.
