Catalytic activity of graphene oxide hybridized ZnWO4 for dyes degradation and oxidation of functionalized benzyl alcohols

Abstract

A simple sol-gel method was used to prepare the GO hybridized ZnWO 4 nanoparticles (NPs). The size and morphology of prepared GO/ZnWO 4 NPs can be controlled by adjusting the reaction time and temperature. The NPs were characterized using XRD, FTIR and UV-DRS to study their optical properties. The resultant sample is a phase pure GO/ZnWO 4 was confirmed by XRD. As-prepared GO/ZnWO 4 shows band gap energy of 2.32eV, which shown a path to study the catalytic studies i.e. dyes degradation and oxidation of functionalized benzyl alcohols. The obtained results declared the prepared GO/ZnWO 4 NPs have better catalytic efficiency in dyes degradation of Caramine Indigo (CI) and Crystal Violet (CV) under visible-light illumination.
