Electrochemical synthesis of urania coin-like nanoparticles in aqueous media

Urania nanostructures were synthesized by a facile, which is a simple and clean and straightforward deposition method, for two different deposition time durations. The morphology and structures of the products were characterized by the X-ray diffraction analysis (XRD) and Scanning Electronic Microscopy (SEM). The SEM images indicated that the morphology of the synthesized samples for 10 minutes was composed of a coin-like structure with a nano-scale dimension in a narrow- size distribution. The results indicated that the deposition time affects the morphology while it does not affect the structure. The XRD results identified the sample structures as UO2 </sub>crystal. The chemical composition of different points of the sample surface was determined by the energy dispersive spectroscopy (EDS) technique and the results clarified that the samples have a homogeneous composition of uranium oxide. The synergistic properties of the substrate surface, and uranium ions are responsible for the formation of an outstanding and a novel structure.
