The Immobilized H4[PMo12-XWxO40] in Zirconium Modified Mesoporous Silica as a Catalyst in Oxidative Desulfurization

Mesoporous silicate (SBA-15) material was synthesized and modified with ZrOCl2, and then 11-molybdovanadophosphoricacid was immobilized on its surface. The characterization results show that hetropolyacid wasdispersed homogeneously in the mesoscopic silica channels. Finally, the catalytic performance of the sample was testedthrough the oxidative desulfurization (ODS) of the model oil. The results indicate that the mentioned catalyst exhibitedhigh activity and reusability in oxidative desulfurization under mild reaction conditions.
