摘　　要：在碳纤维(Carbon Fiber,CF)表面,采用电沉积方法沉积纳米Pt,形成Pt@CF复合催化剂,用于甲醇的直接电催化氧化。利用金相显微镜对沉积Pt前后的Pt@CF复合催化剂形貌进行了表征。最后,系统地应用电化学方法分析了催化剂的稳定性、甲醇浓度、电位扫描速度和电位扫描范围对催化剂电催化氧化甲醇性能的影响。The Pt@ CF complex catalysts obtained by electrtodepositing nano -Pt onto carbon fiber （CF）, were used for the direct electric catalytic oxidation of methanol. The morphologys of bare CF and Pt@ CF catalyst were characterized by metallographic mi- croscope. At last, the influence of some parameters such as methanol concentration, potential scanrates, and switching potential on itsox- idation as well as long - term stability of the modified electrodehave studied by electrochemical methods.
