Abstract:The activities of Pd/C?Pd Co/C catalysts have been evaluated in a self made batch reactor and characterized by BET?XRD and XPS techniques. The results show that Pd Co/C catalyst exhibits the glucose conversion activity of 92%, with 94% selectivity to glucose acid after reaction for 3 h. The BET measurement reveals the increased distribution of the larger pore size of Pd Co/C catalyst in comparison with that of Pd/C as a result of the addition of Co and the sequent catalyst calcination. The XPS characterization indicates higher concentration and dispersion of palladium species on the surface of Pd Co/C catalysts compared with Pd/C catalyst. This suggests the easy reduction of the Pd species located on the surface of Pd Co/C catalysts. The Pd Co/C catalyst exhibits better catalytic performance for oxidation of glucose than Pd/C catalyst.
Keywords:glucose  Pd  Co/C catalyst  catalytic oxidation
