The extremely abundant reservoir of uranium resources in seawater is regarded as an important strategic pathway for alleviating future uranium shortage and supporting the sustainable development of nuclear energy. However, the ultra-low concentration of uranium in seawater, the presence of complex coexisting ions, and severe biofouling pose significant challenges to achieving efficient and selective uranium extraction. Covalent organic frameworks (COFs), a class of crystalline porous materials featuring tunable structures, well-defined pore channels, high specific surface areas, and excellent chemical stability, have demonstrated unique advantages in uranium extraction from seawater (UES) in recent years. This review systematically summarizes the latest research progress on COFs-based materials for UES, with particular emphasis on their applications and underlying mechanisms in adsorption, photocatalysis, and synergistic uranium extraction driven by external fields such as light and electricity. Strategies including functional group modification, skeleton and defect engineering, composites & heterojunctions, morphology control, donor-acceptor (D-A) structures, reaction-pathway regulation, etc. are discussed to analyze key advances in enhancing uranium extraction capacity, selectivity, kinetic performance, and resistance to biofouling. Finally, the challenges faced by COF-based materials in terms of large-scale application, long-term stability, and cost control are discussed, and future design directions and development trends for high-performance materials for UES are proposed. This review provides a systematic reference and conceptual insights for the in-depth study and practical application of COF-based materials in the field of UES.

Key words: uranium extraction, seawater, covalent organic frameworks, adsorption, photocatalysis, electrochemistry
