Investigation on catalytic activity of CuO/La2O3, CuO/Gd2O3 and CuO/La2O3/Gd2O3 nanocatalysts prepared via novel two step approach

This work was focused on facile two-step synthesis approach of CuO/La2O3, CuO/Gd2O3 and CuO/La2O3/Gd2O3 nanocomposites (NCs) that were prepared. The Powder X-ray Diffraction (PXRD) pattern demonstrated the survival of single-phase monoclinic, hexagonal and cubic phase for CuO/La2O3, CuO/Gd2O3 and CuO/La2O3/Gd2O3 NCs. The band-gap values of prepared NCs were evaluated via UV–Visible Spectroscopy using Tauc’s relation and surface morphologies of...
