Green Synthesis of Ag-Doped ZnO Nanoparticles Using Bael (A. marmelos) Leaves for Wastewater Remediation

Abstract

The microwave-assisted technique proved highly successful in harnessing the Bael (A. marmelos) tree’s natural properties to synthesize Ag-ZnO nanoparticles in an environmentally friendly manner. Through analysis of the various vibration modes evident in the Fourier transform infrared spectra, it became evident that functional groups are present on the nanoparticle surface, showcasing the intricate chemical composition achieved through this innovative synthesis approach. The nanoparticles dimensions, morphology, and surface features were investigated through advanced techniques such as high-resolution transmission electron microscopy and scanning electron microscopy. Analysis revealed that the synthesized Ag-ZnO nanoparticles typically ranged between 15 to 20 nm in size. When subjected to ultraviolet radiation, the silver-doped zinc oxide nanoparticles demonstrated remarkable photocatalytic prowess, effectively decomposing the dye known as methylene blue. The produced Ag-doped ZnO NPs are very good at reducing dye to 88% in about one hour. Characterization, as well as encouraging photocatalytic and antioxidant qualities, indicate the potential use of these synthesized Ag-doped ZnO NPs for environmental as well as vital uses.
