| Abstract Scope |
Microwaves have been regarded as an efficient energy source for materials processing applications. The present study investigates the synthesis of ZnO nanoparticles utilizing a novel microwave-metal discharge-based approach. The methodology relied on the generation of microwave plasma in atmospheric air, which led to the conversion of zinc wire into oxidized vapours. These emitted oxide vapours were subsequently deposited on a collector substrate. This method is a rapid, single-step process and does not involve the use of any toxic chemical reagents, resulting in negligible environmental impact. The obtained powder was examined using various characterization techniques. X-ray diffraction confirmed the crystallinity and formation of the hexagonal (wurtzite) structure of the synthesized nanoparticles. Transmission electron microscopy revealed that the nanoparticles were single-crystalline in nature. X-ray photoelectron spectroscopy confirmed the elemental composition and stoichiometric formation of the synthesized ZnO nanoparticles. |
