Stable Uranium Oxide Under Atmospheric Conditions: An Electroplating Technique for U Film Fabrication at Boron-Doped Diamond Electrodes.

An electrodeposition technique of low-enriched uranium onto boron-doped diamond (BDD) electrodes for uranium electro-assembling, sequestration, uranium electrowinning (as the electroextraction alternative), and future neutron detection applications has been developed. Our findings through physicochemical characterization and an in-depth XPS analysis show that the U/BDD system consists of a blend of uranium oxides with IV, V, and VI oxidation states. Results show that U is present and stable under open atmospheric conditions.
