摘　　要：将纳米Pt/玻碳电极应用于甲醇、甲醛和甲酸的电催化氧化,发现所制备的催化剂电极具有较高的电催化活性。探讨了甲醇、甲醛和甲酸在纳米Pt/玻碳电极上的催化机理。The nano-Pt /GC electrode,which was prepared by electrochemical cyclic voltammetry, has been applied to the electrochemical oxidation of methanol, formaldehyde and formic acid. The results demonstrate that the electrode exhibits the high electro-catalytic activity, the mass current density of nano-Pt /GC electrode is ca 4-5 orders of magnitude as high as that of the Pt electrode. The origins of various peaks in relation to the oxidation of methanol, formaldehyde and formic acid are also explained.
