Abstract

In situ Fourier TransformInfrared (FTIR) spectroscopy was used to study the anion effect in ethanol oxidation on Pt(111) surface modified by rhodium and tin, Pt(111)/Rh/Sn. The in situ FTIR spectra showed that ethanol oxidation reaction pathway is strongly influenced by the nature of the electrolyte anion. In perchloric and sulfuric acid electrolytes were observed the formation of acetaldehyde, acetic acid and CO2; however in phosphoric acid the acetic acid is not observed. The sulfuric acid is the most favorable electrolyte for acetaldehyde and CO2 formation. (C) 2015 Elsevier B.V. All rights reserved. (AU)
