This paper presents the studies of ethanol and acetaldehyde electrooxidation onto Pt(110) electrode modified by different osmium coverage. These oxidation reactions were studied by in situ Fourier transform infrared spectroscopy. It was shown that the catalytic activity of Pt(110) after osmium deposition for ethanol oxidation is greater than that observed on unmodified Pt(110). It was also demonstrated...
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 (θOs = 0.40–0.50), an increase in the voltammetric current of ethanol oxidation was observed, indicating an enhancement of the catalytic activity of the...
