Abstract
This work presents and discusses the study of ZnO (zinc oxide) as nanoparticles and its idiosyncratic characteristics. Zinc oxide nanoparticles were synthesized employing a facile Sol- gel method, with zinc chloride, zinc nitrate and sodium hydroxide at room temperature as starting materials .The prepared ZnO nanoparticles were then characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) ,UV–visible spectroscopy and Fourier transform infrared (FTIR) spectroscopy.SEM and TEM images provide morphological interpretation of the synthesized nanoparticles while its average crystalline size was ascertained from XRD peaks at full width at half maximum and incorporating the Debye-Scherrer’s model. Moreover, interpretation through UV–Visible absorption spectra supported a high absorption confirming its transcendent electrical and optoelectronic properties. The spectral characteristic peaks of the produced zinc oxide nanoparticles were studied using Fourier transform infrared (FTIR) spectroscopy at optimum condition. This paper further focuses on the application of zinc oxide nanoparticles on improving tribological performance as lubricant additives on the grounds of smoothing out the shearing surface and improving colloidal stability.
