Synthesis and Activity of Ag-doped Bi2WO6 Photocatalysts
Ag-doped Bi2WO6 photocatalysts were synthesized by hydrothermal method using from Bi(NO)3·5H2O,NH4VO3,and AgNO3 and further characterized by X-ray diffraction,Scanning electron microscopy,Energy dispersive X-ray detector (EDS) and UV-Vis diffusion reflectance spectra techniques.The photocatalytic activity of Ag-doped Bi2WO6 photocatalysts was evaluated by degrading RhB (10 mg/L) under visible light irradiation (λ > 420 nm).The results showed that in comparison with pure Bi2WO6 the photocatalytic activity of Ag-doped composite photocatalysts was improved significantly,and the degradation rate of RhB was increased about 26% when the Ag+ dopant concentration was 15%.
