Abstract
Abstract Photocatalytic oxidation of dibenzothiophene (DBT) with hydrogen peroxide using TS-1 as photocatalyst at ultraviolet lamp irradiation has been studied. The result showed DBT was photooxidized successfully, regardless of steric limitations. Optimal reaction conditions were investigated in detail. Photooxidized products of DBT are DBT 5-oxide, DBT 5,5-dioxide and SO42− by mass spectrum. Kinetics parameters of the photocatalytic oxidation of DBT were measured and calculated. The kinetics of photocatalytic oxidation of DBT is fist-order. Mechanism of photocatalytic oxidation of DBT by TS-1 was analyzed.
