Abstract

 Development of green chemistry in the synthesis of nanoparticles with the use of plants is a cost-effective and eco-friendly approach. In this research, we described the one pot green synthesis of Zinc oxide nanoparticles (ZnO–NPs) using aqueous extracts ofOriganum majorana, Ziziphus jujuba (Z. jujuba), Elaeagnus angustifoliafresh leaves, Cucumber fruit and Pomegranate peel, and then size of nanoparticles was compared with chemical synthesized ZnO nanoparticles.The average sample crystal size was calculated by X–ray diffraction (XRD) using Debye-Scherrer equation. Scanning electron microscope (SEM) micrographs showed the spherical shape of ZnO–NPs. Functional groups determined by Fourier transform infrared spectroscopy (FTIR) and the presented simple approach described that there is the relationship between the optical absorption spectrum of ZnO nanoparticles caused by surface plasmon absorption (in particular, the plasmon resonance and its broadening) and their sizes.
