Preparation and Photocatalytical of Bi2WO6-xF2x/ZnWO4 Composite Materials by Hydrothermal Method

working with waste water contain dyes presents challenges, so to find some photocatalyst artificial synthesized is a fascinating research job. Using Na 2 WO 4 2H 2 O, Zn(NO 3 ) 2 6H 2 O, Bi(NO 3 ) 3 6H 2 O and HF as raw materials, three different mole ratio of photocatalyst of Bi 2 WO 6-x F 2x / ZnWO 4 have been successfully synthesized by hydrothermal method. The catalysts were characterized by powder X-ray diffraction (XRD) and diffuse reflectance spectrum (DRS). The sample has been made visible light photocatalytic performance test for RhB solution which concentration is 10 mg/L. The experimental results show that the legal system have ZnWO 4 and different mole ratio of the Bi 2 WO 6 / ZnWO 4 and Bi 2 WO 6-x F 2x / ZnWO 4 by hydrothermal method, Bi 2 WO 6-x F 2x / ZnWO 4 composite nano powder have been got after the doped of fluorine ion in Bi 2 WO 6 and ZnWO 4. In photocatalytic experiment which the best photocatalytic effect of Bi 2 WO 6-x F 2x / ZnWO 4 is 0.10/1 as Bi 2 WO 6 / ZnWO 4 mole ratio, this conclusion is consistent in the diffuse reflection spectrum.
