Microwave‐Irradiated Green Synthesis of a Silver/Zinc Oxide Nanocomposite from Atalantia monophylla (L.) Leaf Extract

Abstract

A silver/zinc oxide nanocomposite (Ag/ZnONC) was synthesized using the aqueous leaf extract of Atalantia monophylla as a reducing and capping agent, under controlled and effective microwave heating with silver nitrate (AgNO 3 ) and zinc nitrate hexahydrate (ZnNO 3 Á6H 2 O) serving as precursor salts. The X-ray diffraction spectra peak and selective area electron diffraction patterns confirmed the crystalline nature of the synthesized nanocomposite particles. High-resolution scanning electron microscopy images and high-resolution transmission electron microscopy micrographs of Ag/ZnONC showed an aggregated net-like structure containing small spherical Ag nanoparticles (AgNPs) supported by the large aggregated ZnO nanoparticles (ZnONPs). The eco-friendly synthesized Ag/ZnONC shows great relevance in areas like photonics, catalysis, electronics, and biomedicals.

Basella alba Leaves‐Assisted Eco‐Fabrication of Ag/ZnO Nanocomposites for Anti‐Bactericidal Activity and Catalytic Degradation of Anthropogenic Pollutants

“…These dyes are characterized by a higher degree of aromaticity, intense color stability, chromophores conjugation, and excellent structural stability, which makes them refractory to degradation. Also, the chemical stability and high temperature resistance features of synthetic dyes inhibit the penetration of light, resulting in decreased dissolved oxygen capacity, which leads to the destruction of aquatic biota [2,3]. Hence, it is very difficult to remove these dyes and pollutants through natural degradation processes.…”
