چکیده انگلیسی
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 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.
