Abstract

working with waste water contain dyes presents challenges, so to find some photocatalyst artificial synthesized is a fascinating research job. Using Na2WO4•2H2O, Zn(NO3)2•6H2O, Bi(NO3)3•6H2O and HF as raw materials, three different mole ratio of photocatalyst of Bi2WO6-xF2x / ZnWO4 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 ZnWO4 and different mole ratio of the Bi2WO6 / ZnWO4 and Bi2WO6-xF2x / ZnWO4 by hydrothermal method, Bi2WO6-xF2x / ZnWO4 composite nano powder have been got after the doped of fluorine ion in Bi2WO6 and ZnWO4.In photocatalytic experiment which the best photocatalytic effect of Bi2WO6-xF2x / ZnWO4 is 0.10/1 as Bi2WO6 / ZnWO4 mole ratio, this conclusion is consistent in the diffuse reflection spectrum.
