Document Abstract
In the present paper we reported the method to prepare ZnO nanoparticles by alkaline precipitation method
for the degradation of an azo dye. We have used ZnO nanoparticles assisted with UV light irradiation to investigate the
photocatalytic degradation of azo dyes. The ZnO photocatalyst was characterized by X-ray diffraction (XRD), scanning
electron microscopy (SEM), and photoluminescence.
