Abstract :

Copper oxide nanoparticles were synthesized using black tea extract and copper nitrate as thecopper source by the green method at different calcination temperatures. This method has manyadvantages such as nontoxic, economic viability, ease to scale up, less time consuming andenvironmental friendly approach for the synthesis of CuO nanoparticles without using any organicchemicals. The synthesized CuO nanoparticles were characterized by powder X-ray diffraction(XRD), scanning electron microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR).The average crystallite size of CuO nanoparticles was calculated using Scherrer formula. The Xraypowder diffraction (XRD) analysis revealed the formation of monoclinic phase CuO withaverage particle size of 22-39 nm.
