Abstract
Abstract In this work, we investigate the effects of ethanol concentration on the yields of CO 2 , acetic acid and acetaldehyde as electrooxidation products. FTIR spectra show that the main oxidation product at low ethanol concentrations is acetic acid, CO 2 being produced to a minor extent. For concentrated ethanol solutions, the pathway producing acetaldehyde becomes dominant. The CO 2 production passes through a maximum at 0.025 M C 2 H 5 OH and then decreases. The intensity of the IR absorption band for CO ad , which is one of the adsorbed intermediates, is practically independent of ethanol concentration.
