Advanced Electrocatalysts for Uranium Extraction: Design Principles and Future Perspectives

Nuclear power offers a solid option for low‐carbon energy, but limited terrestrial uranium resources and uranium‐containing wastewater constrain its long‐term growth. In contrast, seawater holds an almost inexhaustible uranium resource, but ultralow uranium concentrations and interfering ions make its extraction highly challenging. Electrochemical uranium extraction (EUE) has gained attention for its rapid kinetics, high selectivity, and controllable deposition. This review summarizes recent progress in EUE, emphasizing constant voltage, constant current, and half‐wave rectified alternating current techniques. We highlight advances in electrode materials, such as metals, metal oxides, carbon‐based systems, single‐atom catalysts, MXenes, and porous frameworks. We also discuss structure‐performance relationships and extraction mechanisms. Finally, we offer perspectives on future directions toward efficient and sustainable uranium recovery.
