MOFs 材料由无机金属离子和有机配体通过自组装形成, 具有许多优于传统多孔材料的特性. 超高的比表面 积、较高的孔隙率、可调的孔道尺寸、良好的热稳定性和化学稳定性使得 MOFs 材料在多个领域中展现出了广阔的应 用前景. 随着研究的不断深入, MOFs 材料被广泛应用于催化反应、吸附分离、生物医学等领域中, 并表现出了优异的 效果. 本文着力于近年来 MOFs 材料在吸附分离研究中的进展, 重点介绍了这类材料在能源气体贮存、碳捕获、膜分 离、液相吸附、色谱的分离净化方面的应用, 并对其今后的发展进行了展望. Abstract As a new type of nano porous material,

MOFs are synthesized via the self-assembling combination of inorganic metals and organic ligands, and they have many characteristics superior to the conventional porous materials. The ultrahigh surface area, high porosity, adjustable pore sizes, outstanding thermal and chemical stability enable MOFs to be promising materials for widespread applications. With the deepening of research in recent years, MOFs are successfully applied in diverse fields, such as catalysis, adsorption, separation, and biomedicine imaging, among others. The advances of MOFs used in adsorption and separation are reviewed in this paper, with an emphasis on storage of fuels, carbon capture, membrane separation, liquid-phase adsorption, and chromatographic separation and purification. In addition, the future research directions regarding MOFs in the adsorption and separation field are prospected also.
