Green Synthesis and Characterization of Zinc Oxide Nanoparti-cles from the Leaf Extract of Pongamia Pinnata

Abstract

The present work describes the synthesis of zinc nanoparticles using Pongamia pinnata leaf extract. The preparation of zinc nanoparticles by using pongamia pinnata leaf extract has desired quality with low cost and conventional method. The pongamia pinnata leaf extract was mixed with zinc nitrate hexahydrate solution by stirring and heating 60°C-80°C and the reduction reaction was studied by observing the colour change. The preliminary screening test confirms the presence of flavonoid and polyphenols. The zinc nanoparticles were characterized by UV-visible spectrometer, X-ray diffraction (XRD), Fourier Transform infrared (FTIR). The XRD exhibit the Crystalline in nature. FTIR confirms the presence of functional groups of stabilizer pongamia pinnata in capping the zinc nano particles. ZnO nano particles exhibits absorption peak at 370nm.Therefore, the study reveals an efficient, ecofriendly and simple method for the green synthesis of ZnO nanoparticles using green synthetic approach.
