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

ABSTRACT: 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 U⁵⁺ is present and stable under open atmospheric conditions. The U electrodeposition on BDD creates smooth surfaces, free of voids, with uniform deposition of homogeneous tiny particles of stable uranium oxides, instead of chunky particles, and uranium compound mixtures, like large fibers of the precursor uranyl.
