Biogenic Synthesis and Comprehensive Characterization of Zinc Oxide Nanoparticles Utilizing Hemidesmus indicus Root Extract
Keywords:
Zinc oxide, green synthesis, Nanoparticles, Hemidesmus indicusAbstract
Nanoparticles possess distinct characteristics when compared to their larger bulk forms, and they hold promise for a wide range of applications across various areas of biological science domains. Eco-friendly synthesized nanoparticles have attracted significant attention because of their natural characteristics, including speed, environmental friendliness, and affordability. In this study root extract of Hemidesmus indicus served as both a reducing and capping agent in the environmentally friendly synthesis of zinc oxide nanoparticles. The synthesized zinc oxide nanoparticles were analysed using Ultraviolet-Visible spectroscopy, Fourier Transform Infrared spectroscopy, X-Ray Diffraction spectroscopy and Field Emission Scanning Electron Microscope techniques. The UV-Vis spectra indicated that the zinc oxide nanoparticles exhibited a maximum absorption peak at 274 nm. The bandgap of the ZnO NPs was also investigated. Different functional groups played a role in the capping and stabilization of the zinc oxide nanoparticles, as verified by FTIR analysis. The XRD pattern was compared with the standard confirmed spectrum of ZnO NPs produced in the current experiments. The XRD pattern indicates that the ZnO nanoparticles are free of contaminants. The morphology of the nanoparticles is examined using FE-SEM.
