金属有机框架化合物(MOF)是近年来发展起来的一类由无机金属中心与有机官能团通过共价键或离子键相互联接、共同构筑的具有规整孔道结构的新型多孔晶体材料,在气体吸附和储存、分离、催化、光电、传感等领域具有广泛的应用前景。其中沸石咪唑类金属有机框架化合物(ZIF)由于其均匀规整孔道结构和较高热稳定性,沸石咪唑类金属有机框架膜的合成和应用研究最近引起人们的极大兴趣,逐渐成为气体分离膜的研究热点。但由于沸石咪唑类金属有机框架膜通常
Metal organic framework compound (MOF) is a new type of porous crystal material with regular channel structure, which is co-constructed by inorganic metal centers and organic functional groups by covalent bonds or ionic bonds. In the process of gas adsorption and storage , Separation, catalysis, optoelectronics, sensing and other fields have a wide range of applications. Among them, the zeolite imidazole metal organic framework compound (ZIF) has attracted great interest due to its uniform regular pore structure and high thermal stability, and has gradually become the research of gas separation membrane Hot spots. But due to the zeolite imidazole metal organic framework film usually
