Abstract�� In this paper,a series of complex catalysts of Pt-SnO_2/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.
