In this paper, the reaction mechanism of methanol oxidation on platinum surface, the poisoning of catalyst and the progress of anti-CO catalyst are summarized. The structure and surface composition of catalyst and the influence of electrode potential on the catalytic activity are also discussed. Current catalysts are not satisfactory, and basic research will help to avoid purely empirical approaches to finding more desirable catalysts
