| 英文摘要 | a bimetallic pd-promoted gold catalyst with mesoporous silica nanoparticles (msns) as support, pdau/msn, was prepared by an impregnation-hydrogen reduction method, and its catalysis for the base-free oxidation of benzyl alcohol was investigated. it was found that adding a small amount of pd, with a pd/au atomic ratio as low as 0.05/1, can significantly decrease the size of the gold particles and thereby remarkably enhance the catalyst's activity for aerobatic oxidation. at the optimal pd/au atomic ratio of 0.2/1, the catalyst pd0.2au/msn showed 8 times and 3 times higher activity than the monometallic catalysts au/msn and pd/msn, respectively. the prepared catalysts were comprehensively characterized by xrd, druv-vis, tem, xps, and h-2-tpr to correlate the enhanced activity with the promotional effect induced by adding pd.
