Zinc oxide Nanoparticles: Green Synthesis, Characterization, Physicochemical Performance and Anti-oxidant Properties

Abstract

Background: A growing amount of interest has been shown in the biosynthesis of metal-oxide nanoparticles by the utilization of plant extracts. Zinc oxide nanoparticles are one of the essential materials for preparing nanoscale systems.

Objective: The objective of the current research is to green-synthesize zinc oxide nanoparticles and study their chemical and physical properties.

Methods: In the study, Zinc oxide nanoparticles (ZnO-NPs) were prepared from Musa SP as one of the significant plant extracts using banana peels, and these extracts were used to produce nanoparticles for many minerals and aspects. This study clarifies ZnO-NPs physical and chemical characteristics accurately and demonstrates the significance of ZnO extract in many fields of life. The most important of which are Ag, Au, as well as oxides of some metals such as Cu, ZnO, and Fe2O3.

Result: These nanoparticles were diagnosed using infrared spectroscopy (FTIR) to determine the ions' positions, X-ray diffraction (XRD) to consider the crystal structure, light-emitting scanning electron microscope (SEM) to prove the shape of the surface, and finally UV-Vis spectroscopy to identify the compound ZnO.

Conclusion: Through these measurements, the physical and chemical properties of the material were studied found in this research that the small sized ranging from (40) to (70) nm, and the production of nanoparticles at the peak of the spectral emission of (420) nm, also this results show that ZnO-NPs had anti-oxidant properties, which were determined clearly by two procedures, DPPH and total antioxidant.
