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 CH3COO-, only small quantity of CH3CHO 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.

摘要

采用循环伏安法和原位傅里叶变换红外光谱法研究了碱性溶液中乙醇在纳米铂/玻碳电极上的电氧化过程。结果表明，乙醇氧化的主要产物是CH3COO-，同时仅检测到少量的CH3CHO。与酸性介质中乙醇氧化的双路径反应机理不同，碱性介质中乙醇的氧化是通过解离吸附的中间过程实现的。
