Abstract
Green synthetic process is the realistic solution for the nanomaterials preparation. ZnO nanoparticles of size 45 nm have been synthesized by the microwave synthesis by using pomegranate peel extract. This microwave mediated method was found to be an excellent method for the production of other metal oxides as well. From SEM measurements, the morphology of ZnO is nanoparticles and having the diameter in the range of 200-300 nm. In this work, ZnO NPs were found with 8 mm, 10 mm, 12 mm zone of inhibition against Staphylococcus aureus, Proteus Vulgaris, and Morganellamorganii respectively. We discovered the efficient and alternative route for the green synthesis of ZnO NPs using pomegranate peel extract and has excellent advantages over conventional chemical and physical methods.
