Abstract In the present work, an attempt to synthesis of bimetallic copper zinc tungstate (CuZnWO4) nanoparticles with reduced graphene oxide (CuZnWO4/rGO) via one-step hydrothermal technique. The synthesized CuZnWO4/rGO composite are characterized by Fourier transform infrared spectroscopy (FTIR), Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis diffuse reflectance spectroscopy (UV-DRS) and Photoluminescence (PL). The photocatalytic performance is examined by the degradation of methylene blue (MB) dye under visible-light irradiation. The MB dye isalmost 73 % degraded within 80 minutes. Further, the electrochemical performance of hybrid CuZnWO4–rGOcomposite showed the specific capacity (SC) of 480 Fg− 1 at 4 Ag− 1 in 6 M KOH electrolyte with excellent cyclabilityconserving a capacitance retention of 127% after 5000 cycles due to increase diffusion of electrolyte ions to the electrode materials. These results support that the hybrid CuZnWO4–rGO composite as an appropriate electrode material for high-performance SCs electrode and an auspicious catalyst for the degradation of dye (organic) contaminants in aqueous media.
