摘要:

近年来,随着农业化、工业化和城市化进程的推进,各行业排放的农药、兽药、重金属离子和染料等水体污染物对生态环境和人类的生产生活带来了巨大的危害,因此采取绿色且高效的方法去除污染物具有重要意义。金属-有机骨架(Metal-organic framework, MOFs)是一种由金属离子和有机配体组成的多孔结晶材料,具有可调节孔径和大比表面积等优势,在各个领域具有广泛的应用。然而,单金属MOFs虽性能优异,但孔隙小,活性位点少,而引入第2种金属离子形成的双金属MOFs材料具有孔道丰富、比表面积大、结构可调和丰富的活性位点等优点,广泛应用于催化、储存、载药和运输等领域。增加的吸附位点和增强的协同效应,使得双金属有机骨架材料在吸附领域有着潜在的应用前景。该综述对近8年双金属MOFs最新研究进展进行了总结,讨论了双金属MOFs在合成和应用方面所面临的挑战,并对它们的进一步发展前景进行了展望,为双金属MOFs的制备和污染物吸附应用提供参考。

Abstract:

Recently, with the advance of agriculturalization, industrialization and urbanization, pollutants such as pesticides, veterinary drugs, heavy metal ions and dyes emitted from various industries have brought great harm to the ecological environment and human production and life. Therefore, it is important to adopt green and efficient methods to remove pollutants. Metal-organic framework (MOFs) is a kind of porous crystalline material composed of metal ions and organic ligands, which has the advantages of adjustable pore size and large specific surface area, and has a wide range of applications in various fields. However, while monometallic MOFs have excellent performance but small pores and few active sites, bimetallic MOFs formed by introducing a second metal ion have the advantages of abundant pores, large specific surface area, tunable structure and abundant active sites. Recently, they have been widely used in catalysis, storage, drug loading, and transportation. The increased adsorption sites and enhanced synergistic effects make the bimetallic organic frameworks materials potentially promising for applications in the field of adsorption. Therefore, this paper summarizes recent research progress on bimetallic MOFs, discusses the challenges that face in terms of synthesis and applications, and looks forward to their further development, providing references for the fabrication of bimetallic MOFs and applications in pollutant adsorption.

Key words: Metal-organic frameworks (MOFs), Bimetallic MOFs, Pollutants, Adsorption removal
