Synthesis of nickel oxide nanoparticles by Sol-gel method

Nickel oxide NPs are widely recognized as excellent photocatalysts due to their unique optical features such bandgap energy, retention time, strong light absorption, electron-hole recombination duration, and significant negative oxidation potential of excited electrons. NiO nanoparticles were successfully created using a combination nickel hexahydrate precursor, ethanol, distilled water. was employed precursor create (NO3).6H2O, water, stirring until solution homogeneity used make alkaline sodium hydroxide, the into homogenous on magnetic stirrer at 75 °C. A thick green produced pH=12.The surface morphology nanoparticle size as-prepared estimated SEM AFM images spherical particles with sizes about 26.80 nm 37.96 nm. The cubic crystal structure disclosed X-ray Diffraction (XRD). NP absorption spectra in UV visible rangesShow blue has maximum wavelength 341 band is seen 627 Fourier transform infrared (FTIR) spectroscopy.
