Fabrication and characterization of zinc oxide nanoparticles for photocatalytic application

Abstract

The physicochemical characteristics of Zinc nanoparticles (ZnO NPs) were investigated using various techniques after they were produced using the sol gel process. The crystalline structure, surface morphology, optical property, elemental and chemical composition of the samples have been studied by X-diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance (DRS),energy dispersive X-ray (EDX) and fourier transform infrared (FTIR) spectroscopies respectively. The synthesis of extremely pure, well crystalline and photo-active ZnO NPs with mixed surface morphology was obtained. Afterward, the photocatalytic activity of ZnO NPs were evaluated against Rhodamine 6G (RH-6G) in aqueous medium.
