【摘要】：磁性金属-有机骨架(MMOFs)复合材料是一类新颖的功能材料;MMOFs在磁性功能粒子的基础上结合了金属有机骨架材料的孔径均一、比表面积高、化学和热稳定性良好、吸附亲和力强等性能,在催化和环境等领域中显示出潜在的应用前景.本文简要概述了近年来制备的MMOFs复合材料,包括磁性微球核壳结构、磁性纳米颗粒镶嵌结构、磁性颗粒无规则互混结构、磁性石墨烯基复合结构;并从环境污染物的吸附、富集和催化降解角度,重点总结了MMOFs在环境分析和环境修复中的应用.
[Abstract]:Magnetic metal-organic framework (MMOFs) composite is a novel functional material, which combines the pore size, specific surface area, chemical and thermal stability of the metal and organic skeleton materials on the basis of magnetic functional particles. Because of its strong adsorption affinity, it has shown potential applications in the fields of catalysis and environment. In this paper, MMOFs composite materials prepared in recent years, including magnetic microsphere core-shell structure, magnetic nano-particle mosaic structure, magnetic particle irregular intermixing structure, magnetic graphene based composite structure, and adsorption of environmental pollutants, are briefly reviewed. The application of MMOFs in environmental analysis and environmental remediation was summarized in terms of enrichment and catalytic degradation.
