Green Synthesis of MgO NPs by Olea Europeae Leaves Extract from Bulk MgO and Study Physical Properties

Abstract

In this study, the biological synthesis have been used to prepared the nanoparticles of magnesium oxide in the presences of Olea europeae leaves, it was used as a reductant and capping agents at concentration (100 ml), and that contains antioxidants. The properties of nanoparticles have been characterized. X-ray diffraction Spectroscopy (XRD) showed that the structure of MgO NPs is polycrystalline with cubic phase and average crystallite size was found 12.08 nm, the Energy Dispersive Spectroscopy (EDX) appeared patterns originating from Mg and O, while Fourier Transform Infra-red Spectroscopy (FTIR) explained functional groups at the surface which return to Olea europeae leaves extract and MgO NPs. The morphological properties have been analyzed via Field Scanning Electron Microscopy (FE-SEM), the images in (FE-SEM) showed spherical shapes with an average diameter of 28.13 nm. The optical properties of MgO NPs have been characterized via Ultraviolet-visible Spectroscopy (UV-vis), the absorbance edge exhibited shift to the ultraviolet region with decrease in energy band gap (Eg) to 5.4 nm as compared with bulk (7.8 nm).
