Synthesis of ZnO Nanoparticles by a Green Process and the Investigation of their Physical Properties

This contribution reports on the synthesis and the physical properties of ZnO nanoparticles prepared using a green chemistry process. Aspalathus Linearis's extract was used as an effective chelating agent. The whole reaction process for the ZnO nanoparticle was conducted at room temperature. The microstructural properties of ZnO was investigated using X-ray diffraction, furthermore Electron Dispersive X-rays Spectroscopy was employed as quantitative elemental analysis. From the Transmission Electron Microscopy results, the ZnO nanoparticles were found to be highly crystalline with an average diameter of similar to 23.7 nm.
