Abstract:
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.
摘要:
双金属金属有机骨架(BMOF)是一类功能多孔材料,通过包含两种不同金属离子和有机配体的节点之间的配位而构建。研究表明,由于电荷分布的调整和活性位点的增加以及双金属之间的协同作用,BMOFs的催化活性大大提高。以及它们比表面积大的优点,高孔隙率,独特的结构和分散的活性中心使它们成为应用于废水处理领域的重要有机材料。在这次审查中,总结了近年来BMOFs的制备和构建方法,我们专注于去除水环境中不同类型的污染物,包括离子,染料,药品或个人护理产品,酚类化合物和微生物,以及它们相应的去除机制。此外,我们展望了他们在废水处理方面的未来机遇和挑战。
