摘要
金属有机框架(MOFs)是一种由金属离子或金属簇和有机配体自组装形成的三维多孔材料。由于大部分MOFs材料的物理化学稳定性较差,极大地限制了其在气体吸附与分离中的应用。UiO-66系列材料具有出色的水热稳定性和化学稳定性,是目前报道的MOFs材料中稳定性最好的材料之一。介绍了UiO-66系列材料用于吸附与分离CO_2所取得的突破性进展以及材料的改性方法,指出了该材料在结构优化和性能研究方面存在的问题,展望了UiO-66系列材料在能源和环境中的应用前景。
Metal-organic frameworks (MOFs)are a class of porous crystalline materials self-assembled from metal ions/clusters with organic linkers,mostly arranged in a crystallized three dimensional manner.But there is a crucial weakness which hinders the practical application of MOFs in absorption and separation,namely,the low stability.UiO-66has remarkable hydrothermal stability and highly resistant to many solvents.Development and characteristics of UiO-66series and its structure-active relationship,breakthrough progress of UiO-66series in CO2 adsorption and separation were introduced.And the application bf UiO-66series in energy and environment was prospected.
