Photocatalytic Activity of S-doped TiO2 Photocatalyst under Visible Light

Teruhisa Ohno, Takahiro Mitsui, Michio Matsumura

Abstract

Abstract In order to effectively utilize visible light in photocatalytic reactions, we have developed S-doped TiO2 particles. They show strong absorption for visible light and high activities for degradation of methylene blue in aqueous solution under irradiation at wavelengths longer than 440 nm. The oxidation state of the S atoms incorporated into the TiO2 particles is determined to be S6+ from the XPS spectra.
