Abstract
AbstractA simple approach composite hydroxide mediated technique is applied successfully for the preparation of efficient CuO and CuO–CeO2 photocatalysts. The structural, morphological, and optical characteristics of synthesized photocatalysts are probed by X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), and UV–vis spectroscopy. The XRD and XPS reveal the successful formation of pure CuO and CuO–CeO2 nanocomposite structures. Spherical, nanorods, nanosheets poly edge type peculiarities are found in SEM images. EDX backs the results of XRD and XPS. Bandgap energy of synthesized photocatalysts is found between 1.49 and 1.36 eV indicating red shift. Compared with pure CuO photocatalysts the CuO–CeO2 composites effectively degrade the MB dye. The efficiency of CuO/CeO2 (90:10) nanocomposite exhibit 99.01% efficiency and follow the pseudo first order kinetic reaction.
