Development of Silver Based Catalysts Promoted by Noble Metal M (M = Au, Pd or Pt) for Glycerol Oxidation in Liquid Phase

The liquid-phase oxidation of glycerol was studied to obtain glycolic acid as a value-added molecule. The effect of metal addition to silver based catalyst was investigated under strong basic condition. The best catalytic performance was obtained over silver catalyst promoted with a small amount of platinum Ag95–Pt5/CeO2. Namely, the conversion close to 54% was reached after 5 h of reaction at 60 °C, with the selectivity to glycolic acid of 51%. Further increase in the amount of promotor (up to 50%) changed the reaction mechanism to product selectively the glyceric acid.
