Abstract

Present knowledge of methanol and CO electrooxidation reactions is given in the light of electrochemical, spectroscopic and microscopic data. Strong catalytic effects on CO electrooxidation by nonmetallic adatoms (S, Se, Te) are presented and discussed. For methanol oxidation, several authors have shown, besides CO2, nonnegligible yields of formaldehyde and formic acid, depending among other factors on concentration, potential, electrode roughness and temperature. Infrared spectra assist mechanistic interpretations. Promotion of methanol oxidation by ruthenium presents a maximum effect on alloy materials at room temperature for a surface concentration of Ru between 15% and 45%.
