| Abstract: | In this study, copper oxide nanoparticles were produced using an environmentally friendly method involving the mixing of copper salt precursors and aqueous leaf extract of Khaya senegalensis. The influence of pre and post synthesis parameters such as solution pH (5, 9, 11, 13), copper salt types (chloride, nitrate and sulphate), calcination temperataure (300-550 ᵒC) and holding time (1-3 h) on the morphology, sizes and phase structure of CuO nanoparticles were examined. The synthesized materials were characterized by energy dispersive spectroscopy (EDS), high resolution scanning electron microscope (HRSEM), Brunauer Emmett Teller (BET) N2 adsorption -desorption, X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The HRSEM/XRD analysis of the calcined CuO nanoparticles showed the formation of spherical and crystalline stable tenorite phase at optimum calcination temperature (550 ᵒC), and optimum holding time (3 h) for all the salt and solution pH 11. This study demonstrated that the shape, size and phase of CuO nanoparticles were dependent on the nature of the copper precursor, solution pH, calcination temperature and holding time |
