Abstract

A novel, simple, less time-consuming and cost-effective green method has been developed to synthesize Cu2O nanoparticles and composite with poly vinyl alcohol relatively at low temperature in acidic pH. Cu2O nanoparticles were prepared by reduction of Benedict’s solution using agriculture wastes of Manihot esculenta leaves containing reducing sugars which act as reducing agent. The nanocomposite was prepared by addition of Cu2O nanoparticles to the stirred solution of PVA. The solution was stirred for 0.5hour and dried at room temperature. The resulting Cu2O nanoparticles and Cu2O/PVA composite were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), UV-VIS absorption and Fourier-transform infrared (FTIR) spectroscopy.
