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, 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 (FCC) face-centered cubic structure confirmed there no derivative phase observed XRD. Metal-Oxygen bond revealed FTIR analysis. morphology elemental composition sample were carried out using SEM with EDAX. optical bandgap prepared nanocomposite studied UV–Vis spectroscopy. Electrochemical behaviour at conditions, voltage (1.3 V), frequency (42 Hz–5 kHz). Photocatalytic antibacterial behavior also investigated. It found that this novel composite catalyst decomposed 92% toxic pollutants from wastewater. Further, composites showed superior performance against aeromonas hydrophila, E. coli, S. epidermis bacterial pathogens.

Abstract Zinc Oxide (ZnO) nanoparticles were synthesized by hydrothermal method under different conditions and studied various properties. FTIR studies proved the presence of ZnO bonding purity samples. Grain size was found to be decreased with increase reaction temperature increased time. TEM images show formation nanorods same temperature, also nanoflowers nanospheres for temperatures. Intensity luminescence peaks is changed variation in interplanar spacing. UV–vis spectra helped identify photon absorption particles bigger size. Change bandgap value observed due difference nanoparticles.
