Abstract
A systematic investigation of ethanol oxidation on Ti/RuO2 electrodes has been carried out in 1.0 mol dm(-3) HClO4 acid solution. The experi mental results show high selectivity toward acetaldehyde formation. On e of the secondary oxidation products of ethanol forms a blocking film at the electrode surface which can be removed during electrosynthesis using pulse control of the working potential. The influence of the el ectrolysis conditions, the electrode mechanism of ethanol oxidation, a nd R-Omega values measured under pseudo-Tafel plots are discussed.
