Activity and Selectivity Trends for Diol Oxidation over Supported Pt Catalysts at Acidic Conditions

The TOF and diacid selectivity of α,ω-diol oxidation over Pt/C increased with increasing chain length. Monoalcohols of the same chain length were oxidized more rapidly than the corresponding diols. In-situ ATR IR spectroscopy revealed CO adsorbed on Pt prior to the reaction, but it was rapidly oxidized in aqueous conditions.
