摘　　要：利用电化学沉积法合成Pt/MnO_2/C电极催化材料,用循环伏安法对电极的催化性能进行测定,并通过SEM对电极材料的表面形貌进行了表征．实验结果表明,利用电化学沉积法可以得到比表面积较大的Pt/ MnO_2/C电极催化材料,该电极对CH_3OH氧化呈现较高的催化活性。A method of composing the catalyzer of Pt/MnO2/C by electrolysis-sediment is discussed and the surface structure of Pt/MnO2/C is observed by SEM method in this paper. The electrocatalytic performance test has been studied by CV method, and the result shows that the electrode of Pt/MnO2/C has increased electrocatalytic activity for oxidation of methanol. The electrode of Pt/MnO2/C, which has bigger specific surface area, can be obtained by electrolysis-sediment.
