One Pot Synthesis of Phosphomolybdenate Based Hybrids for Efficient Oxidative Desulfurization

With increasing stringent standard of sulfur content in fuels, there is a growing need for high-efficiency deep desulfurization to meet ecological and environmental demands. Herein, a series of heteropolyacid catalysts with phosphomolybdic acid base melamine (MHPMo-n) were synthesized by one-pot method and applied to oxidative desulfurization. Further, the optimum conditions for desulfurizations could be explored, which the desulfurization rate of the catalyst could reach 100% within 60 min under the conditions of m(catalyst)= 0.01 g, T = 40 °C, O/S = 3. Furthermore, the catalyst demonstrated excellent catalytic efficiency during the five cycles. One-pot method of phosphomolybdic acid base melamine provides a new idea for the synthesis of catalysts with outstanding catalytic properties for oxidative desulfurization (ODS).
