A magnetic hybrid material Fe2O3/C was prepared by pyrolysis of MIL-101 (Fe) in the presence of nitrogen flow and (Bu4N)3PWxMo4-x catalysts were encapsulated into it through impregnation method. The (Bu4N)3PW4@Fe2O3/C catalyst exhibited excellent catalytic activity for the desulfurization of model fuel, showing a DBT removal efficiency of 99.9% within 30 minutes. It also demonstrated good activity for other substrate sulfides and remained stable with a removal efficiency of>90% after 8 cycles.
Magnetic hybrid material dropped Fe2O3 particles in mesoporous carbon was prepared by pyrolysis of MIL-101 (Fe) in the presence of nitrogen flow. Then, high activity peroxo-polyoxometallates (Bu4N)3PWxMo4-x (x = 0, 2, 4) were encapsulated into the magnetic porous carbon material Fe2O3/C through facile impregnation method to prepare magnetic supported catalysts (Bu4N)3PWxMo4-x@Fe2O3/C. The catalysts were characterized by several means and applied for extraction oxidation desulfurization (EODS) of model fuel. One synthesized catalyst, (Bu4N)3PW4@Fe2O3/C, exhibited nearly perfect catalytic activity, which could remove 99.9 % DBT in simulated fuel within 30 min at mild conditions, and it also showed good activity for other substrate sulfides including BT, 4-MDBT and 4,6-DMDBT. Furthermore, the catalyst (Bu4N)3PW4@Fe2O3/C has stable structure and good reus-ability, which shown removal efficiency of DBT of>90 % up to 8 cycles.
