Sulfur-doped TiO2 prepared by a sol-gel method to degrade dimethyl sulfide (DMS) under visible light irradiation was investigated. The degradation reactions of DMS were performed under various operation conditions. The results indicate that S-doped TiO2 photocatalysts are mainly nano-size with an anatase-phase structure. Relative humidity and inlet DMS concentration significantly influence the DMS conversion and mineralization. Langmuir-Hinshelwood kinetic models have been used in the analysis of the experimental data obtained. The main oxidation products of DMS photodegradation are SO2, CO2, DMDS, DMSO, DMSO2, CO, and MSA. Two possible mechanisms have been developed for photodegradation of DMS in a dry and a humid environment.
