Abstract

Abstract: The adsorption and oxidation of ethylene glycol(EG) on Pt electrodes were investigated by in situ FTIRspectroscopy and cyclic voltammetry, The results demonstrated that EGwas oxidized on Pt electrode in acidic media via a dual path reaction mechanism, i.e.EG may be oxidized into CO₂ through the dissociative adsorbate(CO_ad)and the reactive intermediates (mainly CH₂OHCOOH and HOOC-COOH species).Based on the data of in situ FTIRexperiments, the present work revealed the origin of characters observed in cyclic voltammetric experiments concerning the adsorption and oxidation of EGon Pt electrode.

Key words: Ethylene glycol, Electrooxidation, Pt electrode, Acid media, Cyclic voltammetry, In situ FTIR
