摘要: 膦酸类金属-有机骨架(MOFs)材料作为众多MOFs材料家族中的一类,近年来受到了研究者的广泛关注。本文综述了膦酸类MOFs材料的发展过程及其对二氧化碳(CO2)的吸附性能,并阐明了吸附过程机理,总结了结晶度、有效比表面积、孔隙率和水稳定性等因素对膦酸类MOFs材料CO2吸附性能的影响。概述了含有NN'-二(亚甲基膦酸)-哌嗪及其衍生物、膦酸单酯(PMEs)配体的新兴膦酸类MOFs材料的性质和特点,总结了哌嗪环、烷基基团、烷氧基及杂元素(硫、氟)对提高膦酸类MOFs材料CO2吸附性能的研究概况。分析了甲基、乙基、烷氧基等对膦酸类MOFs材料孔道结构的调控机制。指出了较低的比表面积和孔隙率仍然是制约膦酸类MOFs材料CO2吸附性能的重要因素,而开发核壳结构的MOFs材料可能是一种有效的解决途径。

Abstract: Phosphonate metal-organic framework (MOFs),one kind of the MOFs materials,has attracted much attention in recent years. In this work,the progress of phosphonate MOFs and its application in CO2 adsorption were reviewed. Moreover,the adsorption mechanism was expounded. The effects of crystallinity,effective specific surface area,porosity and water stability on the CO2 adsorption performance of phosphonate MOFs were discussed. In addition,the properties and characterization of new phosphonate MOFs containing N,N'-piperazinebis (methylenephosphonic acid) and its derivatives,phosphonate monoesters (PMEs) linkers were also reviewed. The effect of properties of piperazine ring,alkyl group,alkoxy group and hetero element (sulfur and fluorine) on CO2 adsorption performance of the phosphonate MOFs was summarized. The adjusting mechanism of the methyl,ethyl and alkoxy group on the pore structure of phosphonate MOFs were analyzed. However,the low specific surface area and porosity are still important restriction factors for the CO2 adsorption performance of phosphonate MOFs,while the core-shell structure of the MOFs material may give an effective solution.

Key words: MOFs, phosphonate metal-organic frameworks, carbon dioxide, adsorption
