Over the last few decades, there has been a growing discourse surrounding environmental and health issues stemming from drinking water and the discharge of effluents into the environment. The rapid advancement of various sewage treatment methodologies has prompted a thorough exploration of promising materials to capitalize on their benefits. Metal-organic frameworks (MOFs), as porous materials, have garnered considerable attention from researchers in recent years. These materials boast exceptional properties: unparalleled porosity, expansive specific surface areas, unique electronic characteristics including semi-conductivity, and a versatile affinity for organic molecules. These attributes have fueled a spike in research activity. This paper reviews the current MOF-based wastewater removal technologies, including separation, catalysis, and related pollutant monitoring methods, and briefly introduces the basic mechanism of some methods. The scale production problems faced by MOF in water treatment applications are evaluated, and two pioneering methods for MOF mass production are highlighted. In closing, we propose targeted recommendations and future perspectives to navigate the challenges of MOF implementation in water purification, enhancing the efficiency of material synthesis for environmental stewardship.
在过去几十年里，围绕饮用水以及废水排放到环境中所引发的环境与健康问题，相关讨论日益增多。各种污水处理方法的迅速发展促使人们深入探索有前景的材料，以利用其优势。金属有机框架材料（MOFs）作为多孔材料，近年来受到了研究人员的广泛关注。这些材料具有卓越的性能：无与伦比的孔隙率、巨大的比表面积、包括半导体性在内的独特电子特性，以及对有机分子的广泛亲和力。这些特性推动了研究活动的激增。本文综述了当前基于MOF的废水处理技术，包括分离、催化以及相关污染物监测方法，并简要介绍了一些方法的基本机理。评估了MOF在水处理应用中面临的规模化生产问题，并重点介绍了两种MOF大规模生产的开创性方法。最后，我们提出了针对性的建议和未来展望，以应对MOF在水净化应用中的挑战，提高材料合成效率，促进环境保护。
