Sol-gel Synthesis and Characterization of Zinc Oxide Nanoparticles Using Black Tea Extract

Abstract

The use of plant extract is generating the interest of researchers toward cost effective,<br />nontoxic, economic viability and eco-friendly green synthesis of nanoparticles. In the present<br />work, zinc oxide (ZnO) nanoparticles were synthesized using black tea extract and zinc nitrate<br />as the zinc source by the sol-gel method. The synthesized ZnO nanoparticles were<br />characterized by powder X-ray diffraction (XRD), UV-visible spectroscopy and Fourier<br />Transform Infrared Spectroscopy (FTIR). The average crystallite size of ZnO nanoparticles<br />was calculated using Scherrer formula. The X-ray powder diffraction (XRD) analysis<br />revealed the formation of wurtzite hexagonal phase ZnO with average particle size of 32 nm.<br /><br /><br />
