green synthesis and characterization of zinc oxide nanoparticles from leaf extracts of satureja hortensis

Background and aim: zinc oxide nanoparticles are widely used in various industrial and medical fields. in order to prevent and reduce the environmental effects of commercial nanoparticles synthesized via conventional chemical methods, this study was designed to prepare green synthesized zinc oxide nanoparticles using satureja hortensis. materials and methods: in this study, the aqueous extracts of the satureja plant were prepared as reducing agents. zno nanoparticles were synthesized using zinc nitrate and sodium hydroxide. the powder samples were analyzed using an infrared spectroscopy (uv-vis), scanning electron microscopy (sem), energydispersive x-ray analysis (edx), fourier transform infra-red spectroscopy (ftir), and x-ray diffraction (xrd). results: the findings of this research, including the change in solvent color, the absorption spectrum at 330 nm, electron microscopy images, the determination of zinc and oxygen as the main elements in the composition, and the peaks in the x-ray diffraction spectrum, confirmed the synthesis of zinc oxide nanoparticles. conclusion: the green synthesis of nanoparticles using plants is easier to use. it is non-toxic, and more environmentally friendly. moreover, it should be replaced with physical and chemical methods of synthesis of nanoparticles.
