环境污染和资源短缺是当今世界面临的两大问题。核能是一种能量密度高的绿色能源，已经引起了世界的广泛关注和发展。作为一种重要的核燃料，铀(VI)在世界上大多数核电站中都有使用。海洋中含有大量的低浓度铀，因此从海水中选择性地浓缩铀(VI)对核能的发展和稳定的能源供应具有重要意义。本文综述和比较了近年来从海水中提取铀(VI)的功能材料，包括COF、MOF、聚合物和多孔炭的研究进展。结合间歇实验、先进的光谱技术和理论计算，阐述了各种材料作为吸附剂、光催化剂和电催化剂从海水中萃取铀(VI)的机理。主要从吸附容量、选择性、稳定性和适用性等方面讨论了该材料在海水提取铀(VI)中的实际应用。最后，总结和展望了海水提取铀(VI)功能材料目前面临的挑战和机遇，为今后新型功能材料的设计提供指导。
Environmental pollution and resource shortage are two major problems in the current world. Nuclear energy, a green energy with high energy density, has attracted extensive attention and development of the world. As an important nuclear fuel, U(VI) is used in most of the world's nuclear power plants. The ocean contains a large amount of low-concentration uranium, so selective enriching U(VI) from seawater is of great significance to the development of nuclear energy and stable energy supply. In this review, the recent research progress of functional materials with potential applications for U(VI) extraction from seawater, including COFs, MOFs, polymers and porous carbon, are summarized and compared. Combined with batch experiments, advanced spectroscopic techniques and theoretical calculations, the mechanism of U(VI) extraction from seawater using various materials as adsorbents, photocatalysts and electrocatalysts is expounded. The practical application of the materials in U(VI) extraction from seawater is discussed mainly from the aspects of sorption capacity, selectivity, stability and applicability. In the end, the current challenges and opportunities of functional materials for U(VI) extraction from seawater are summarized and prospected, to provide guidance for the design of new functional materials in future.
