Abstract

This work reports the electrochemical and spectroscopic studies of ethanol electrooxidation on the platinum single-crystal electrodes (111, 100, 110) surface-modified by different coverage degrees of osmium. In general, after deposition of osmium (θ Os = 0.40–0.50), an increase in the voltammetric current of ethanol oxidation was observed, indicating an enhancement of the catalytic activity of the electrode. According to Fourier transformed infrared results, the mechanistic pathway for this reaction depends directly on the degree of osmium coverage. Thus, for low osmium coverage (θ Os < 0.20), the formation of CO as an intermediate is favored, giving CO2 as the main final product; for intermediate osmium coverage (θ Os = 0.25–0.50), the acetaldehyde formation is enhanced; and for higher osmium coverage (θ Os > 0.92), the catalytic activity for ethanol oxidation tends to decrease, producing insignificant amounts of CO and CO2. Moreover, at this surface, the direct oxidation of ethanol to acetic acid (pathway not interesting for energetic ends) is also observed at lower potentials.
