摘　　要：运用电化学循环伏安法研究了酸性介质中乙醇在铂微粒修饰玻碳电极上的电催化氧化行为.考察了铂的沉积条件、载铂量、支持电解质、乙醇的起始浓度、扫描速度对乙醇在GC(Pt)电极上电催化氧化性能的影响,优化了GC(Pt)电极的制备方法和乙醇氧化体系的配制.The electrocatalytic oxidation of ethanol on Pt/GC in acid solution was investigated by using cyclic voltammetry. The experimental results demonstrated that the method of preparing for a new type of high activity and lower cost practical electrocatalysts is feasible. The electrocatalytic behaviors of ethanol on Pt/GC were investigated by varying the quantity of platinum on glassy carbon, electrolytes, the initial concentration of ethanol and the scan rate. The preparation of GC(Pt) electrode and the electrochemical system were optimized in this paper.
