This study presents a comparative analysis of zinc nanoparticles synthesized using Livistona chinensis leaf extract as a green and sustainable approach. The nanoparticles were synthesized through the reduction of zinc nitrate, and their properties were thoroughly characterized using various spectroscopic and microscopic techniques. UV spectroscopy identified distinct absorption peaks, confirming the successful synthesis of zinc nanoparticles. Infrared spectroscopy (IR) offered insights into the functional groups engaged in the reduction and stabilization process, while X-ray diffraction (XRD) validated the crystalline nature of the nanoparticles. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) provided a detailed examination of the morphological and structural attributes, showcasing unique features and size distribution of the zinc nanoparticles. Dynamic light scattering (DLS) was employed for studying the hydrodynamic size and stability of the nanoparticles in solution. The comparative analysis through various spectroscopic and microscopic techniques provides comprehensive insights into the synthesized zinc nanoparticles. This research contributes to the growing field of green synthesis methods, highlighting Livistona chinensis leaf extract as a promising and sustainable precursor. The detailed characterization is essential for understanding the potential applications of these zinc nanoparticles in various fields, including biomedical and nanotechnology.
