Abstract

The present work outlines the co-precipitation synthesis of undoped and -doped CuO NPs with two transition metals (TM), iron (Fe) and nickel (Ni), their characterization, and then their use as photocatalysts for the degradation of pollutants. The structural, morphological, and optical properties of the synthesized CuO NPs are characterized using X- ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and UV–Visible Diffused Reflectance Spectroscopy (DRS), techniques. The photocatalytic activities of the prepared oxide powders are evaluated against methylene blue (MB) taken as a model pollutant in aqueous media. The photodegradation efficiency is estimated and compared to other recent works.
