Abstract

The photocatalysts of S-doped K2Ta2O6 have been successfully synthesized by hydrothermal method. Effects of S doping to the K2Ta2O6 on the structure and photocatalytic performance are systematically investigated. The S was successfully introduced into the lattice sites of Ta5+ at the state of S6+. The morphology was unchanged when the S was incorporated into the K2Ta2O6. The band gap of K2Ta2O6 was narrowed with the increase of S dopants. The photocatalytic test under UV-light irradiation indicated that the decomposing efficiency of MO and RhB was elevated with the incorporation of S. And the sample prepared from addition of 10% molar ratio of S precursor showed the highest photocatlytic performance.
