The metal-organic framework material UiO-67 was prepared by solvothermal synthesis,and the polyoxometalate was loaded on its surface by the post-modification method to obtain UiO-67-bpy-NiMo11 composite material.The structure of the prepared material was characterized by FT-IR,XRD,TGA,N2 physical adsorption and SEM characterization methods.The self-made MOFs material was used to catalyze the oxidation of dimethyl sulfide (DMS) to prepare dimethyl sulfoxide (DMSO).The effects of five UiO series MOFs catalysts,solvent types,reactions time and the amount of oxidant on the oxidation reaction were investigated to determine the optimal reaction conditions.The results showed that UiO-67-bpy-NiMo11 had excellent catalytic activity for the oxidation reaction of dimethyl sulfide,and it still maintained good catalytic activity after being recycled for five times.
