摘要:

金属有机骨架材料(MOF)是一种高比表面积、活性位点丰富、易化学修饰的新型多孔材料,但较差的水稳定性限制其在吸附挥发性有机化合物(VOCs)领域的应用,因此如何提高和巩固MOF的吸附性能已成为研究的热点。本文从单体MOF的合成、MOF复合材料的制备、吸附机理和吸附影响因素等方面综述了MOF及其复合材料吸附去除VOCs的研究进展。针对目前MOF材料在吸附VOCs方面的不足提出研究建议,展望其在VOCs吸附领域的发展方向为制备富含微-介孔结构和活性位点、水热稳定性强、抗水蒸气竞争吸附好和循环利用率高的新型高稳定性材料,以及开发新型MOF材料合成方法。

Abstract:

Metal organic framework (MOF) is a new type of porous material with high specific surface area, abundant active sites and easy chemical modification. However, its poor water stability limits its application in adsorption of volatile organic compounds (VOCs). Therefore, one hot topic of MOF research is to improve its VOCs adsorption performance. This article reviews the research progress of MOF and its composites for the removal of VOCs from the aspects of synthesis of monomeric MOF, the preparation of MOF composites, the adsorption mechanism and the influence factors in adsorption. In view of the shortcomings of MOF materials in the adsorption of VOCs, research suggestions are put forward. The development directions of MOF materials in VOCs adsorption are to prepare new MOF materials with rich micro-mesoporous structure and active sites, strong hydrothermal stability, good resistance to water vapor’s competition adsorption and high recycling utilization, and to develop new synthesis methods.

Key words: metal organic framework (MOF), composites, volatile organic compounds (VOCs), adsorption mechanism, influence factors
