Preparation and characterization of copper oxide nanoparticle-determination of its structural and optical properties

A facile, innovative and affordable green route has been demonstrated for the formation of Copper oxide nanoparticles by biogenic method using aqueous leaf extract of Calotropis Gigantea which acts as a reducing and stabilizing agent. Copper nanoparticles received much attention owing to its high electrical conductivity, high liquefaction point, low electrochemical migration behavior and low cost. The property of copper nanoparticles mainly depends on the synthesis route and their process parameters. The prepared Copper oxide nanoparticles were characterized by a host of different techniques such as X-ray diffraction (XRD), Diffuse reflectance spectroscopy (DRS), Zeta potential and Fourier transform infrared spectroscopy (FT-IR). The XRD pattern confesses that Copper oxide nanoparticles associate to orthorhombic structure. The DRS absorption spectrum shows band gap energy corresponds to wide band gap semiconductor The FT-IR spectra indicate the presence of chemicals which are responsible for biochemical reaction. The Zeta Potential value revealed the stability of Copper oxide nanoparticles
