Facile synthesis of NiO-CYSO nanocomposite for photocatalytic and antibacterial applications

Abstract

Ceria based metal oxide nanocomposites (combination with rare earth oxides) have become irreplaceable and tend to display great functioning in all kinds of arenas like as photocatalytic, electrochemical and biological. NiO-CYSO [NiO-Ce0.8Y0.2O2-??Ce0.8Sm0.2O2-?] nanomaterial was produced by the wet-chemical route for numerous purposes. The development of fluorite cubic crystal configuration detected and no secondary phase and metal-oxygen bond was disclosed by XRD and FTIR correspondingly. The morphological and elemental analysis of the prepared composite was carried out using SEM with EDAX. The optical bandgap of prepared nanocomposite was studied using UV?Vis spectroscopy. Electrochemical behaviour observed at conditions, voltage-1.3 V, and the frequency range ? 40 Hz to 6 kHz. The photocatalytic and antibacterial behavior of prepared NiO-CYSO nanocomposite also investigated, which gave outstanding results.
