Abstract

Abstract A novel cubic-shaped nanocrystalline ZnWO 4 photocatalyst has been successfully synthesized at 250 °C in a very short time by a microwave -assisted precipitation technique using Na 2 WO 4 ·2H 2 O and ZnCl 2 as raw materials. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) results indicated that obtained powder exhibited only wolframite structure with a cubic morphology. The direct optical band gap was estimated to be 3.74 eV by UV–vis diffuse reflectance spectroscopy (UV–vis DRS). The photocatalytic activity was investigated by the decomposition of aqueous Rhodamine B (RhB) under UV light irradiation. Cubic-shaped nanocrystalline ZnWO 4 showed high photocatalytic activity and the degradation efficiency was 69% after 75 min.
