磁性金属有机复合材料的合成与应用

金属有机框架材料(MOFs)是一种将金属离子中心与有机配体通过配位键结合起来的一类具有网格结构的材料。由于金属离子以及有机配体的多样性,MOFs的结构也具有多样性。磁性金属有机复合材料是一种新型的复合材料,既结合了MOFs的网状结构及结构多变性的优点,又结合了磁性材料易于分离且可重复利用的特性,使得这种材料在药物载体、多相催化、选择吸附等多种方面都有着较为广泛的应用。以经典的几类MOFs为分类依据,研究了它们与磁性材料结合形成新型复合材料的方法,同时概括了这些新型复合材料在不同领域的应用,最后提出了该材料目前所存在的问题,并对今后的研究方向进行了展望。

Synthesis and application of magnetic metal organic composite

Metal-organic frameworks(MOFs)are a kind of materials with grid structure,which combines metal ion centers with organic ligands through coordination bonds.Due to the diversity of metal ions and organic ligands,MOFs have diverse structures.Magnetic metal organic composite is a new kind of composite material,which combines the advantages of metal-organic frame material with network structure and structural variability,and the characteristics of easy separation and reusability of magnetic materials.These complexes have been widely used in many fields such as drug carrier,heterogeneous catalysis,selective adsorption and so on.Several classical metal-organic frame materials were summarized as the classification basis,and the methods of combining them with magnetic materials to form new composite materials.At the same time,the applications of these new composite materials in different fields were also summarized.The current problems of the material were proposed,and prospected the future research directions.
