Synthesis of CuO nanoparticles: Structural and optical properties by sol-gel method

Abstract

Among the transition metal oxide nanoparticles, copper oxide NPs were synthesized by an economical sol-gel method. (Cu (No3)2 3H2O) was used as a precursor and the pH was maintained until it reached 12 finally the precipitate of copper oxide was produced. Copper oxide nanoparticles that was prepared were characterized by XRD, UV-Vis, and SEM. the structural analysis of copper oxide were executed by X- ray diffraction. The crystalline size was determined by Debye- Scherrer formula and the peaks denoted the structure of CuO to be monoclinic. From the absorbance spectrum of UV-vis the bandgap of CuO nanoparticles is determined. Supportive corroboration of CuO nanoparticles is seen in FTIR.
