| 摘 要： | 运用电化学循环伏安和原位ＦＴＩＲ反射光谱研究了碱性介质中乙醇在ｎｍ－Ｐｔ／ＧＣ电极上的氧化。结果表明，主要产物是ＣＨ３ＣＯＯ＾－，仅存在少量乙醛，未检测到ＣＯ谱峰。与酸性介质中乙醇氧化的双途径机理不同，碱性介质中乙醇的氧化未经过解离吸附的中间步骤。

| Abstract: | The electro oxidation of ethanol on a nm Pt/GC electrode in alkaline solutions was investigated by using cyclic Voltammetry and in situ FTIR spectroscopy.The results demonstrated that the main product of ethanol oxidation was CH 3COO -,only small quantity of CH 3CHO was determined simultaneously.In contrast with the dual path reaction mechanism for the oxidation of ethanol in acid media,the oxidation of ethanol in alkaline media was revealed via the intermediate process of dissociative adsorption. |
