NiO nanoparticles are prepared by the chemical sol-gel method using ammonium hydroxide and nickel nitrate salt as precursors. The NiO nanoparticles are calcined at 1000oC. The nanoparticles are characterized by X-Ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and UV-VIS spectro-photometry. The XRD confirms NiO and crystallite size is found to be 20.7nm when annealed at 1000o...
