ABSTRACT

Development of green nano technology is producing attention of researchers near eco- friendly biosynthesis of nano particle. Many foundations were discovered for the synthesis of ZnO nanoparticles. In this study, biosynthesis of ZnO nanoparticle was done using Annona Reticulata seed extract. Seed extract was mixed with Zn nitrate and we observe the change in colour from deep yellowish to white ZnO NPs. These biosynthesized ZnO NPs were characterized with the help of X-ray diffraction, Infrared spectroscopy, UV visible spectra, Dynamic light scattering and SEM. SEM micrographs reveal the globular shaped agglomerated particles. UV visible and FTIR spectroscopy confirms the bonding in extract and NPs. DLS and zeta potential indicates size and charge on nanoparticles explore new area for reactions. Thus this method can be used for rapid and eco-friendly biosynthesis of ZnO NPs.

Keywords: technology, extract, color, agglomerated particles, ecofriendly.
