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 340 X 10(-3) min(-1), which was seven times as that of amorphous titania and much higher than that of reported titania composites or metal-organic framework-based catalysts.
