Zinc Oxide nanoparticles (ZnO NPs) were produced in the form of a powder by co-precipitation synthesis method. The photocatalysts underwent characterization Employing X-ray diffraction (XRD), scanning electron microscopy, and Energy dispersive X-ray spectroscopy (EDX). The assessment of photocatalytic activity was conducted aqueous heterogeneous medium containing Nigrosin dye and ZnO NPs as photocatalyst in a batch reactor. An investigation was conducted to examine the many elements that influence. The efficacy of photocatalytic decomposition. These factors include amount of catalyst used, the initial concentration of dyes, the impact of H2O2, and the effect of temperature. The optimal concentration of Nigrosin dye equal 30 mg L−1, and catalyst concentration of 0.13 g /100mL. The activation energy for the photo degradation process calculated using the Arrhenius equation was equal to (30.36 KJ/mol).
