      Abstract:

        NiO nanoparticles were prepared by the direct precipitation   method. The as-prepared nanoparticles were
        characterized by X-ray diffraction (XRD), FTIR and UV-Visible   spectrometer analysis techniques. The
        average particle size of nanoparticles was calculated from the   XRD study was 18 nm. According to the
        UV-Visible spectrum, the band gap value of 5.41 eV was obtained   for the NiO nanoparticles. The catalytic
        activity of NiO nanoparticles has been studied for the selective   oxidation of benzyl alcohol to the
        benzaldehyde using air as the oxidizing agent. The NiO oxide   nanoparticles showed excellent catalytic
        activity for the oxidation of benzyl alcohol to the benzaldehyde.   The complete conversion of all the
        benzylic alcohols to the corresponding benzaldehyde is achieved   within a 3 hour reaction period at 80 ⁰C.
        The obtained product of the reaction is identified by TLC, IR and   Tollun’s test which was shown
        benzaldehyde.
