摘要
运用循环状安和现场ＦＴＩＲ反射光谱研究了碱性介质中乙二醇在铂电极上的吸附和氧化行为。结果表明，乙二醇的氧化与溶液酸碱性密切相关。除成功地检测到ＣＨ２ＯＨ－ＣＯＯ＾－，＾－ＯＯＣ－ＣＯＯ＾－等中间产物及ＣＯ２、ＣＯ＾２－３等最终产物外，还发现乙二醇氧化过程中有乙烯中间体生成。
The electrooxidation of ethylene glycol (EG) in alkaline media has been investigated with in situ FTIR spectroscopy and cyclic voltammetry. The main products such as CO_2 and were detected clearly. Besides CH_2OHCOO￣- and ￣-OOC-COO- species, a new intermediate, (with its IR absorption band at 2027cm￣(-1) in 0.1 mol/L and at 2036 cm￣(-1) in 0.05 mol/L NaOH solution), was determined and a possible mechanism to form this intermediate was proposed.
