Abstract

• Green synthesis of metal oxide nanoparticles using plant extract is a promising alternative to traditional method of chemical synthesis. The biosynthesis of zinc oxide nanoparticles using fruits and leaves extracts of Terminalia chebula Retz. has been reported in this study. It is simple, costeffective, rapid and eco-friendly way to synthesize zinc oxide nanoparticles The ZnO nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV-Vis) and Fourier transform infra-red (FT IR). The structure of ZnO nanoparticles was indexed as hexagonal structure. The crystallite sizes of ZnO nanoparticles from fruits and leaves extracts of T chebula were calculated by Scherrer formula as 170 nm and 23.4 nm respectively Morphology of nanocrystals was observed to be aggregated spherical particles UV absorption spectra of ZnO nanoparticles using fruits and leaves extracts of T chebula indicated the absorption maxima at 376 and 375 nm, respectively This new eco-friendly approach of synthesis is a novel, cheap, and convenient technique suitable for large scale commercial production
