▎ 摘　　要

In this study, we reported the fabrication of reduced graphene oxide/ZnWO4 (GZW) nanocomposites via a facile coprecipitating method to enhance the electron-hole separation under indirect sunlight irradiation. The physicochemical properties of different % GZW were characterized by FT-IR, SEM, EDS, and TEM spectroscopy. The incorporation of rGO enhances the degradation efficiency of MB dye under irradiation of visible light (blue LED (lambda = 450 nm) and red LED (lambda = 610 nm)) for 60 min and the best results were obtained by 10GZW4 which was calcined at 250 degrees C. Furthermore, the higher photocurrent response intensity and small arc radius of electrochemical impedance (EIS, Nyquist plots) using GZW compared to that of ZnWO4 reflected the synergistic effect of GO to enhance the visible light response of ZnWO4. On the other hand, GZW exhibited high antibacterial activity against three bacterial strains and the high activity was obtained using a 10GZW4-250 catalyst.
