Abstract

Electrodeposition is a key technique for preparing actinide thin films, which are used in applications such as alpha spectroscopy, accelerator beam bombardments, irradiation studies, and as radioactive sources. In this study, we investigate the electrodeposition of actinides using three nonradioactive lanthanide surrogates: lanthanum, samarium, and lutetium. Using cyclic voltammetry, chronopotentiometry, pH evolution measurements, and imaging, we examine the electrodeposition mechanisms driven by local pH changes at the electrode surface, caused by cathodic reactions that form hydroxide species. While all three lanthanides produced similar thin film morphologies, lutetium showed a stronger preference for deposition at lower currents compared to lanthanum and samarium. This difference suggests that the unique properties of lanthanide hydroxides influence the deposition process. These findings underscore the importance of accounting for the variability in lanthanide and actinide hydroxides as the range of actinides used in electrodeposition continues to expand.

期刊介绍： The Journal of Nuclear Materials publishes high quality papers in materials research for nuclear applications, primarily fission reactors, fusion reactors, and similar environments including radiation areas of charged particle accelerators. Both original research and critical review papers covering experimental, theoretical, and computational aspects of either fundamental or applied nature are welcome. The breadth of the field is such that a wide range of processes and properties in the field of materials science and engineering is of interest to the readership, spanning atom-scale processes, microstructures, thermodynamics, mechanical properties, physical properties, and corrosion, for example. Topics covered by JNM Fission reactor materials, including fuels, cladding, core structures, pressure vessels, coolant interactions with materials, moderator and control components, fission product behavior. Materials aspects of the entire fuel cycle. Materials aspects of the actinides and their compounds. Performance of nuclear waste materials; materials aspects of the immobilization of wastes. Fusion reactor materials, including first walls, blankets, insulators and magnets. Neutron and charged particle radiation effects in materials, including defects, transmutations, microstructures, phase changes and macroscopic properties. Interaction of plasmas, ion beams, electron beams and electromagnetic radiation with materials relevant to nuclear systems.
