Synthesis and Characterization of Onion Mediated Silver Doped Zinc Oxide Nanoparticles

Abstract

Green synthesis of nanoparticles has attracted considerable attention in recent years. In this regard, plants extracts and natural resources such as microorganisms and enzymes have been found to be good alternative reagents in nanoparticles synthesis. Utilizing green substances has several advantages including low energy consumption and moderate operation conditions without using any toxic chemicals. An attempt was made to synthesis and characterizes the silver doped zinc oxide nanoparticles (Ag doped ZnO NPs) by using onion extract. The synthesized Ag doped ZnO NPs were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy Analysis (EDAX), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD) and Zeta potential analyses. These characterizations revealed that doped nanoparticles are differed in their structural properties. The onion extract was used as reducing agent as well as stabilizer. The phytochemicals found in the onion extract were responsible for the formation of Ag doped ZnO NPs.
