Abstract
, respectively. The effect of catalyst dose, pH, water composition, and radical scavengers was also evaluated to optimize the conditions and propose a degradation mechanism and p-n heterojunction with Fermi level shifting for improved exciton generation. The biomedical importance of the ZnO/CuO NCs was assessed by the disc diffusion assay to check the antibacterial potential, and DPPH assay, TFC assay and TPC assay for antioxidant potential. All these studies, along with the reusability of the catalyst, demonstrated the appreciable catalytic efficacy of ZnO/CuO NCs for the water purification of industrial effluents.
