A facile and green sonochemical route for the synthesis of CuWO4 nanostructure

In this research, CuWO4 nanostructure was synthesized by weak ultrasonic irradiation method at 80ºC and DI water. Sonochemistry is the research area in which molecules undergo a chemical reaction due to the application of ultrasound radiation. The physical phenomenon is responsible for the sonochemical process is acoustic cavitation [1]. In this work, we used sonochemical method which is an effective, useful, lowcost and a simple technique but it has not been used to synthesize this compound until now. CuWO4 is a promising candidate for supercapacitor applications [2-3]. Cu(NO3)2.3H2O and Na2WO4.2H2O were used as reagents and the resulting precursor was calcinated at 500ºC for 2h in furnace. The product was characterized using fourier transform infrared (FT-IR), X-ray powder diffraction (XRD) and scanning electron microscopy (SEM).
