Photocatalytic performances of Ag/ALa4Ti4O15 (AÂ =Â Ca, Sr and Ba) on H2O2 oxidative desulfurization

The ODS reaction schematic shows that ultra-deep desulfurization of model fuel is proposed for the production of clean fuel. In the process of reaction, electrons and holes are generated when the perovskite composite oxides absorb photons by UV irradiation. The photogenerated holes react with hydrogen peroxide to form OH radicals, which oxidize DBT to DBTO2. It is, however, demonstrated that catalysts show superior performance for the desulfurization under the condition of the existence of hydrogen peroxide.
