Research progress of metal-organic framework materials for CO_(2) adsorption

综述了近年来MOFs材料对纯CO_(2)吸附及从二元混合气中对CO_(2)进行吸附分离领域的研究进展,讨论了吸附温度,比表面积对材料CO_(2)吸附量的影响,阐明了材料吸附及分离CO_(2)的机理,指出了负载官能团、掺杂金属离子、制备复合材料是提高材料CO_(2)吸附性能的有效手段。目前,将金属-有机骨架材料作为CO_(2)吸附剂仍面临成本过高,吸附性能有待进一步加强等问题,只有解决了这些问题,材料才能实现工业化应用。

This article reviews the recent research progress in the field of metal-organic framework materials for the adsorption of pure CO_(2)and the adsorption and separation of CO_(2) from binary mixtures.The effects of adsorption temperature,material specific surface area on the CO_(2) adsorption capacity of materials is discussed.The mechanism of material adsorption and separation of CO_(2) is clarified.Then,it is pointed out that loading functional groups,doping with metal ions,and preparing composite materials are effective means to improve the CO_(2) adsorption performance of materials.At present,the use of metal-organic framework materials as CO_(2) adsorbents still faces problems such as high cost and need for further enhancement of adsorption performance.Only when these problems are solved can the materials achieve industrial application.
