Abstract

The aims of this study are to investigate the photocatalytic activities regarding to dimethyl sulfide degradation under visible-light irradiation. In this study, TiO₂ and cerium-and sulfur-co-doped TiO₂ were prepared by a sol-gel method and calcined at 500°C. The characteristics of samples were performed by XRD, TGA, UV-visible, and XPS. The photocatalytic activity of the samples simulating indoor air was evaluated under various inlet pollutant concentrations in ppmv and residence time. The XRD results show that co-doped S- and Ce-would reduce the crystalline size. The UV-visible spectra analyses indicate that the absorption in the visible region of S₅/TiO₂ and Ce_nS₅/TiO₂ increases compared with TiO₂. The XPS analyses of all photocatalysts show that S exists as S⁶⁺ and Ce³⁺ are more than Ce⁴⁺. The operating performance of various co-doped TiO₂ show that S₅/TiO₂ may be the best photocatalyst for DMS conversion and mineralization. Further study is under the way.
