【Abstract】 Objective The polyoxometalate-based inorganic-organic hybrids have been synthesized.The catalytic performances of catalysts for the oxidative desulfurization（ODS） have been investigated by using tert-butyl hydroperoxide as oxidants.The optimal conditions of ODS were investigated by using thioether compounds as the substrate. Methods Two phosphomolybdates, [Ag₃（H₃O）（HL）（L）](PMo₁₂O₄₀)·H₂O（1）and（H₃L）₃(PMo₁₂O₄₀)·2H₂O（2）,were synthesized according to the references by using 4-（1H-1,2,4-triazol-1-methyl） benzoic acid（HL）,silver nitrate and phosphomolybdate acid as raw materials.Their catalytic activities for ODS were studied. Results The optimal reaction conditions were 5 mL of model oil, 40 ℃ of temperature, 10 mg of catalyst, and 120 min of treatment time. Conclusion The results showed that two compounds exhibited efficient catalytic activity toward thioethers under the optimal reaction conditions.The catalytic oxidative activities were maintained even after six cycles.更多还原
