Synthesis of fibrous silica tantalum (FSTa) for photooxidative desulphurization

The photooxidative desulphurization (PODS) of dibenzothiophene (DBT) was examined under visible light using fibrous silica tantalum (FSTa), tantalum oxide doped fibrous silica (Ta/KCC-1) and commercial tantalum oxide (Ta2O5). FSTa was synthetized using hydrothermal method, while Ta/KCC-1 was obtaine...
