摘要/Abstract

摘要：

金属有机骨架（MOFs）材料是一种由金属离子或团簇通过配位键与有机配体自组装形成的有机-无机杂化多孔材料。二维MOFs材料具有比表面积大、孔隙率高、孔结构可调、电子传递能力强以及活性位点直接暴露在二维平面上等独特优点,这使得它们在气体吸附、催化、储能及传感等多个领域均有很好的应用前景。随着二维材料的迅速发展,越来越多的新型二维MOFs材料被合成制备出来。结合近几年国内外研究现状,综述了界面生长法、表面活性剂辅助法和剥离法等3种二维MOFs材料的制备方法,分析了各种方法的优点和不足之处,并对其未来的发展进行了展望。今后,开发一种成本低、产率高、易于工业化生产且环境友好的二维MOFs材料制备技术将是该研究领域的重点发展方向。

Abstract:

Metal-organic frameworks（MOFs） are a kind of organic-inorganic hybrid porous materials formed by self-assembly of metal ions or clusters with organic ligands through coordination bonds.Two-dimensional（2D） MOFs have many unique ad-vantages,such as high specific surface,high porosity,adjustable porous structure,high conductivity and many active sites di-rectly exposed on the surface of the 2D plane.These characteristics make them have good application prospect in gas adsorp-tion,catalysis,energy storage,sensing and other fields.With the rapid development of 2D materials,more and more new 2D MOFs materials have been designed and synthesized.Combined with domestic and foreign researches in recent years,three main methods for preparing 2D MOFs were reviewed in this paper,which included interfacial growth method,surfactant-as-sisted method and exfoliation method.The advantages and disadvantages of these methods were analyzed and compared.Final-ly,the research progress of 2D MOFs was introduced and its future development was also prospected.The preparation of 2D MOFs with low cost,high yield,easy industrialization and environmental friendliness was the focus of research in the future.

Key words: metal-organic frameworks, nanosheets, preparation, exfoliation method
