Abstract

Water is integral to humans and other living beings on the planet. Over the last few decades, water pollution has been on the rise. Contaminants pose a risk not only to human health but also to aquatic life. Therefore, water purification has been the focus of researchers, driving the quest for more sustainable and efficient treatment technologies. Metal–organic frameworks (MOFs) have emerged as highly effective adsorbents owing to their versatile properties such as tailorable porosity, high surface area, and diverse functionalities. These robust materials offer significant advantages over conventional ones considering their remarkable efficiency and selectivity in removing organic and inorganic contaminants. Furthermore, MOF-based composites and nanoconfined architectures have extended application horizons. Despite the usefulness of MOFs in water treatment, challenges such as cost-effectiveness, scalability, long-term stability, and reusability remain key concerns. This review focuses on the recent developments in MOF-based materials for water purification, emphasizing structural modifications, underlying mechanisms, and emerging trends. Additionally, it highlights critical challenges and future perspectives, discussing the requirement for sustainable regeneration strategies and improved synthesis approaches. Ongoing efforts to counter the vulnerability of MOFs will lead to revolutionizing water remediation by employing selective, efficient, and regenerable adsorbents, thereby contributing to the global efforts of protecting the environment.

基于金属有机框架的水修复材料:最新进展、挑战和未来展望
水对人类和地球上的其他生物来说是不可或缺的。在过去的几十年里,水污染一直在上升。污染物不仅对人类健康构成威胁,而且对水生生物也构成威胁。因此,水净化一直是研究人员关注的焦点,推动了对更可持续、更有效的处理技术的探索。金属有机骨架(mof)由于其多种特性,如可定制的孔隙率、高表面积和多种功能,已成为高效的吸附剂。考虑到它们在去除有机和无机污染物方面的显着效率和选择性,这些坚固的材料提供了比传统材料显著的优势。此外,mof基复合材料和纳米约束结构具有广阔的应用前景。尽管mof在水处理中很有用,但成本效益、可扩展性、长期稳定性和可重复使用性等挑战仍然是关键问题。本文综述了近年来mof基水净化材料的研究进展,重点介绍了mof基水净化材料的结构修饰、潜在机理和发展趋势。此外,它还强调了关键的挑战和未来的前景,讨论了可持续再生战略和改进综合方法的要求。通过采用选择性、高效和可再生的吸附剂,对抗MOFs脆弱性的持续努力将导致水修复的革命性变化,从而为保护环境的全球努力做出贡献。
