Abstract

An electrochemical oxidation of propylene carbonate (PC) and diethyl carbonate (DEC) with 1.0 mol dm−3 LiC1O4 on the LiCoO2 electrode was investigated using in situ Fourier Transform Infrared (FTIR) spectroscopy. The obtained spectra showed that C-O-C bonds in both solvents were broken at the initial stage of the electrochemical oxidation process to form radical species which have a similar chemical structure to carboxylic compounds. These radical intermediates were changed by a further electrochemical oxidation and/or a following chemical reactions. In the case of PC, the following chemical reaction proceeded to form carboxylic anhydrous adsorbed on the LiCoO2 surface. In the case of DEC, such adsorbates were not observed.
