摘要

Green synthesis of nanoparticles is a safe and eco-friendly approach using plant materials as reducing and stabilizing agents for the synthesis of important nanoparticles. This study investigates the effect of ultrasonication and magnetic stirring methods on synthesis of zinc oxide nanoparticles. In this study the zinc oxide nanoparticles were synthesized by two methods Ultrasonication and magnetic stirring using Punica granatum (Pomegranate) fruit peels. The methods are compared in terms of their abilities to synthesize nanoparticles with desired characteristics. The research explores the potential of both methods for nanoparticles synthesis. The effects of both methods on nanoparticles size, crystallite size, functional group composition, and optical properties were investigated by different characterization techniques. The results show distinct differences in characteristics of nanoparticles between the two methods. SEM analysis reveals that ultrasonication yields nanoparticles with a size range of 57–72 nm, while magnetic stirring produces nanoparticles with a size range of 65–81 nm. XRD analysis shows that ultrasonication- synthesized nanoparticles have a larger average crystallite size (28.12 nm) compared to magnetic stirring synthesized nanoparticles (12.2 nm). UV-Visible absorption spectra demonstrate distinct optical properties with ultrasonication synthesized nanoparticles exhibiting broad absorption peaks and maximum wavelength of absorption at 240–300 nm and high absorbance ) whereas magnetic stirring synthesized nanoparticles show a single absorption peak at a wavelength of 340 nm). These findings suggest that ultrasonication produces nanoparticles with a more uniform size distribution and larger crystallite size, potentially leading to improved material properties. The findings have implications for the optimization of nanoparticle synthesis methods for various applications.
