Enhanced photooxidative desulphurization of dibenzothiophene over fibrous silica tantalum: Influence of metal-disturbance electronic band structure

N. S. Hassan et al.

Summary: Fibrous silica tantalum (FSTa) and metal oxides (AgO, CuO, ZnO)/FSTa catalysts were prepared and characterized for the photocatalytic oxidative desulfurization (PODS) of dibenzothiophene (DBT). The addition of metal oxides decreased the efficiency of PODS, possibly due to mismatched redox potentials. Among the metal oxides loaded FSTa, Zn/FSTa exhibited higher desulfurization rate and could directly oxidize DBT into dibenzothiophene sulfone (DBTO2). The kinetics study showed that the photodegradation over Zn/FSTa followed the pseudo-first-order and adsorption was the rate-limiting step.
