Because the pollutants produced by human activities have destroyed the ecological balance of natural water environment, and caused severe impact on human life safety and environmental security. Hence the task of water environment restoration is imminent. Metal-organic frameworks (MOFs), structured from organic ligands and inorganic metal ions, are notable for their outstanding crystallinity, diverse structures, large surface areas, adsorption performance, and excellent component tunability. The water stability of MOFs is a key requisite for their possible actual applications in separation, catalysis, adsorption, and other water environment remediation areas because it is necessary to safeguard the integrity of the material structure during utilization. In this article, we comprehensively review state-of-the-art research progress on the promising potential of MOFs as excellent nanomaterials to remove contaminants from the water environment. Firstly, the fundamental characteristics and preparation methods of several typical water-stable MOFs include UiO, MIL, and ZIF are introduced. Then, the removal property and mechanism of heavy metal ions, radionuclide contaminants, drugs, and organic dyes by different MOFs were compared. Finally, the application prospect of MOFs in pollutant remediation prospected. In this review, the synthesis methods and application in water pollutant removal are explored, which provide ways toward the effective use of water-stable MOFs in materials design and environmental remediation.

水稳性金属有机骨架在水污染物去除中的应用:综述

因为人类活动产生的污染物破坏了自然水环境的生态平衡,对人类生命安全和环境安全造成了严重影响。因此,水环境修复的任务迫在眉睫。由有机配体和无机金属离子构成的金属有机骨架 (MOF) 以其出色的结晶度、多样化的结构、大表面积、吸附性能和优异的组分可调性而著称。MOFs 的水稳定性是其在分离、催化、吸附和其他水环境修复领域可能实际应用的关键条件,因为在使用过程中需要保护材料结构的完整性。在本文中,我们全面回顾了关于 MOF 作为优秀纳米材料去除水环境污染物的潜力的最新研究进展。首先介绍了几种典型的水稳性MOFs的基本特性和制备方法,包括UiO、MIL和ZIF。然后,比较了不同MOFs对重金属离子、放射性核素污染物、药物和有机染料的去除性能和机理。最后展望了MOFs在污染物修复中的应用前景。在这篇综述中,探索了水污染物去除的合成方法和应用,为在材料设计和环境修复中有效利用水稳定性 MOF 提供了途径。介绍了几种典型的水稳性MOFs的基本特性和制备方法,包括UiO、MIL和ZIF。然后,比较了不同MOFs对重金属离子、放射性核素污染物、药物和有机染料的去除性能和机理。最后展望了MOFs在污染物修复中的应用前景。在这篇综述中,探索了水污染物去除的合成方法和应用,为在材料设计和环境修复中有效利用水稳定性 MOF 提供了途径。介绍了几种典型的水稳性MOFs的基本特性和制备方法,包括UiO、MIL和ZIF。然后,比较了不同MOFs对重金属离子、放射性核素污染物、药物和有机染料的去除性能和机理。最后展望了MOFs在污染物修复中的应用前景。在这篇综述中,探索了水污染物去除的合成方法和应用,为在材料设计和环境修复中有效利用水稳定性 MOF 提供了途径。展望了 MOFs 在污染物修复中的应用前景。在这篇综述中,探索了水污染物去除的合成方法和应用,为在材料设计和环境修复中有效利用水稳定性 MOF 提供了途径。展望了 MOFs 在污染物修复中的应用前景。在这篇综述中,探索了水污染物去除的合成方法和应用,为在材料设计和环境修复中有效利用水稳定性 MOF 提供了途径。
