Study on Synthesis of Diphenyl Carbonate with Heterogeneous Catalytic Reaction——Preparation and Characterization of Catalyst by Microwave

The perovskite-type metal oxides supports and the corresponding supported Pd catalyst were prepared by microwave,and characterized by XRD,SEM and used in the direct synthesis of diphenyl carbonate(DPC).Compared with the catalyst prepared by precipitation,the catalyst prepared by microwave shows more homogenous distribution in particle and pore size and better catalytic activity with the yield of DPC of about 7%.
