Abstract
Reports synthesis of a series of POM-based hybrid materials: phosphotungstic acid supported ceria (HPW-CeO2) which were characterized by X-ray diffraction (XRD), Thermogravimetric-differential scanning (TG-DSC) analysis, Scanning electron microscopy (SEM), FT-Raman, FT-IR, UVvis, and BET analysis.
Combined with [C8mim]BF4, the catalyst was very efficient on the removal of DBT by using H2O2 as the oxidant under mild reaction conditions. The amount of catalyst, O/S molar ratio, reaction time and temperatures were studied in detail. Favorable operating conditions were obtained as well as the kinetic study of substrates.
