Synthesis and Characterization of Zerovalent Iron Nanoparticles using Different Routes
Abstract
Nanoparticles have fangled their roots into various applications and are the most advanced materials which have been of keen interest among researchers these days. Nanoparticles exhibit various physio-chemical properties which vary from their bulk materials. Various methods have been used to synthesize nanoparticles. The chemical preparation of nanoparticles may be harmful. In this experiment, chemical, as well as green routes were applied to synthesize zerovalent iron nanoparticles. In the chemical route of synthesis, two approaches; the chemical reduction method and the co-precipitation method were used. For green synthesis, the leaf extracts of the plant azadirachta indica and calotropis gigantea were used to reduce iron. The peak of iron nanoparticles was observed at 280 nm for iron nanoparticles via UV-visible spectroscopy in both synthesis routes. SEM and TEM spectroscopy was used to determine the size of nanoparticles that were in the nano range.
