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

摘要

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(AgNO3)and zinc nitrate hexahydrate(ZnNO36H2O)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.
