Synthesis of ZnO nanoparticles from zinc acetate dihydrate – An environmental friendly technique

Abstract

The present work describes a plant-mediated method for the synthesis of Zinc Oxide (ZnO) nanoparticles. The native medicinal herb Pistia Stratiotes plant extract and the Zinc Acetate derivative were used to successfully produce the ZnO nanoparticles (NPs). Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy were used to analyze the ZnO nanoparticles that were produced. The morphology and shape of the NPs were examined using SEM. The functional group present in the leaf extract was determined by FTIR spectroscopy and the CH stretching and NH bonding of ZnO were also observed. The antibacterial activity of ZnO NPs was examined against gram-negative and gram-positive bacterial strains such as Klebsiella Pneumoniae and Bacillus Subtilis in different solvent extracts. The synthesized ZnO NPs exhibited significant inhibitory activity against the pathogenic bacterial strains.
