Examining the photo catalytic potency of annealed and un-annealed ZnO and nickel doped ZnO for degradation of organic pollutants in waste waters.

ABSTRACT: Water scarcity and pollution has increased the need for innovative and effective waste water treatment methods. The presented study aims to tackle this difficulty by synthesizing zinc oxide (ZnO) and nickel (Ni) doped ZnO to improve their photo catalytic capacity. This study examines wastewater treatment and organic pollutant breakdown using nanotechnology. The annealing increases photo catalytic activity by 65%, thereby enhancing efficiency. XRD shows that annealing decreased the average crystal size of pure ZnO and nickel doped ZnO (Ni:ZnO) i.e., for pure ZnO average crystal size is decreased from 23.90 to 20.90 nm and for Ni:ZnO, 34.39-28.65 nm. SEM shows that un annealed samples have agglomerates, while annealed samples are quasi-spherical. Using diffuse reflectance spectroscopy (DRS),
