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.
