Bimetallic metal-organic frameworks (BMOFs) are a class of functional porous materials constructed by coordination between nodes containing two different metal ions and organic ligands. Studies have shown that the catalytic activity of BMOFs is greatly improved owing to the adjustment of charge distribution and the increase of active sites as well as the synergistic effect between the bimetals, and the advantages of their large specific surface area, high porosity, unique structure and dispersed active centres make them available as important organic materials applied in the field of wastewater treatment. In this review, the preparation and construction methods for BMOFs in recent years are summarized, and we focus on their removal of different types of pollutants in the aqueous environment, including ions, dyes, pharmaceuticals or personal care products, phenolic compounds and microorganisms, as well as their corresponding removal mechanisms. In addition, we provide an outlook on their future opportunities and challenges in wastewater treatment.
双金属金属有机框架材料（BMOFs）是一类通过含有两种不同金属离子的节点与有机配体之间的配位作用构建而成的功能性多孔材料。研究表明，由于电荷分布的调整、活性位点的增加以及双金属之间的协同效应，BMOFs的催化活性得到了极大提高，并且它们具有大比表面积、高孔隙率、独特结构和分散活性中心等优点，使其成为应用于废水处理领域的重要有机材料。在这篇综述中，总结了近年来BMOFs的制备和构建方法，我们重点关注它们在水环境中对不同类型污染物的去除，包括离子、染料、药物或个人护理产品、酚类化合物和微生物，以及它们相应的去除机制。此外，我们对它们在废水处理方面未来的机遇和挑战进行了展望。
