â¢Oxidative desulfurization performance of amorphous titania can be enhanced by doping MIL-101(Cr).â¢The reaction rate constant over the catalyst with 10% doping content reached 340 Ã 10â3 minâ1.â¢Such catalytic performance could be attributed to the enhanced dispersity of amorphous titania.
High performance MIL-101(Cr)-TiO2 composite material was successfully prepared by doping MIL-101(Cr) in amorphous titania and evaluated for oxidative desulfurization (ODS) of dibenzothiophene (DBT) using cumene hydroperoxide (CHP) as oxidant. The experimental results showed that introduction of MIL-101(Cr) favored the catalytic centers titania to get high dispersion. Remarkably, the reaction rate constant over the catalyst with 10% dopant concentration reached 340Â ÃÂ 10â3 minâ1, which was seven times as that of amorphous titania and much higher than that of reported titania composites or metal-organic framework-based catalysts.
