Herein, we report a simple, economic and low-cost surfactant assisted sonochemical synthesis of ZnWO4 nanoparticles. The structural and morphological features of nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, photoluminescence (PL) spectroscopy and transmission electron microscopy. ZnWO4 had been proven to be one of the most promising electrodes for energy storage and found that the discharge capacity was of 173mA h g^-1 even after 20 cycles at 0.1C rate. In addition to this, good photocatalytic degradation efficiency (98.6% in 120 minutes) was also achieved through Rhodamine B as a model of pollutant system.
