Metal tungstates are important inorganic materials and have potential applications in some fields, such as photocatalysis, light-emitting diodes (LEDs), optical temperature sensors and cathode materials for supercapacitors [1-2]. In this research, ZnWO4 nanoprticles were synthesized successfully by the reaction of Zn(NO3)2.6H2O and Na2WO4.2H2O in ultrasound bath without using any additives. The physical phenomenon is responsible for the sonochemical process is acoustic cavitation. Sonochemistry is the research area in which molecules undergo a chemical reaction due to the application of ultrasound radiation [3]. Sonochemical route is an effective, useful, lowcost and a simple method which we used for the preparation of ZnWO4 nanoprticles. There is no report about the synthesis of ZnWO4 nanoprticles by sonochemical process so far. The result nanoparticles were characterized using fourier transform infrared (FT-IR), X-ray powder diffraction (XRD) and scanning electron microscopy (SEM).
