Mixed metal oxide nanocomposites (rare earth-based) have become irreplaceable and tend to display great functioning in all kinds of arenas like as photocatalytic, electrochemical, and biological. NiO-CGSO [NiO-Ce0.8Gd0.2O2-δ–Ce0.8Sm0.2O2-δ] nanomaterial was produced by the wet-chemical route for numerous purposes. The development of (FCC) face-centered cubic structure confirmed and there was no derivative phase was observed by XRD. Metal-Oxygen bond was revealed by FTIR analysis. The morphology and elemental composition of the sample were carried out using SEM with EDAX. The optical bandgap of prepared nanocomposite was studied using UV–Vis spectroscopy. Electrochemical behaviour was observed at conditions, voltage (1.3 V), and the frequency (42 Hz–5 kHz). Photocatalytic and antibacterial behavior of prepared NiO-CGSO nanocomposites also investigated. It was found that this novel composite catalyst decomposed 92% of toxic pollutants from wastewater. Further, NiO-CGSO composites showed superior antibacterial performance against aeromonas hydrophila, E. coli, and S. epidermis bacterial pathogens.
