Preparation, Characterization and Catalytic Activity of Highly Dispersed Gold Catalyst

Abstract:

Highly dispersed supported gold catalysts have been prepared by solution reduction method using L-lysine as protection agents, and their catalytic activity was evaluated by the liquid phase catalytic oxidation reaction of glucose to gluconic acid. The results suggested that the Au/ZrO₂ catalyst, exhibited high activity for the selective oxidation of glucose. At the reaction temperature of 323K, reaction time of 1h, with the NaCO₃-NaHCO₃ as buffer solution, the yield of gluconic acid was 100%.
