The main study and the development of CeO2 and Cu-doped CeO2 nanocrystals containing transition- metal species are of crucial importance for understanding the preparation and fabrication of CeO2 and Cu-doped CeO2 nanoparticles by solution combustion technique to taken glycine as fuel. The structural properties of Ce1-xCuxO2 nanocrystals were examined by investigating the influence of cerium dioxide and Cu dopant ions. The CeO2 single-phase cubic system was successfully incorporated with Cu ions using the co-precipitation technique, as confirmed by X-ray diffraction results. Field emission scanning electron microscopy and energy dispersive spectroscopy were used to evaluate the surface structure and crystallinity of the produced materials using various characterization techniques. The Ce-O stretching mode is the cause for the significant broad band in the Fourier transform infrared spectrum below 600 cm−1, which confirms the synthesis of pure CeO2. CeO2 nanoparticles are a potential material for photocatalytic and optoelectronic applications because of their required structural and optical characteristics. Under ultraviolet light exposure, the photocatalytic properties of CeO2 and Cu-doped CeO2 nanoparticles were examined using Rose Bengal dye and Rose Bengal Cu/CeO2. In a comparative investigation conducted with and without catalysts, CeO2 and Cu-doped CeO2 show exceptional photocatalytic activity by breaking down over 82% of the Rose Bengal-Cu/CeO2 in 60-min intervals under ultraviolet light.

Keywords: Mixed metal oxides, copper-doped ceria nanocomposites, heterogeneous catalysis, photocatalytic applications
