MOFs作为防毒面具中吸附材料的应用研究

摘要

金属有机骨架材料(MOFs)是由金属离子与有机配体自组装而成的结构规整的多孔骨架材料,其巨大的比表面积使其在有毒气体分子吸附等领域有着广泛应用.可以通过对MOFs材料中有机配体进行酸、碱修饰,增加气体与材料骨架之间的相互作用,提高对有毒气体的吸附选择性及吸附容量.简单介绍了MOFs材料的多样性,分类总结了MOFs材料作为防毒面具中吸附材料对酸性、碱性及中性有毒气体的吸附性能.最后,对MOFs材料作为防毒面具吸附材料的应用前景进行了展望,宽范围、高吸附容量的MOFs材料是用于防毒面具中的理想吸附材料,是今后吸附材料研究的重点方向.%Metal-organic frameworks materials (MOFs) are new kind of porous skeleton materials synthesized by self-assembly with metal ions and organic ligands, whichare used in toxic gases adsorption field due to their huge specific surface area.By means of modification of organic ligands in MOFs skeleton with acid or alkali, the interaction between gases and skeletons will get enhanced, improving the selective adsorption of toxic gases and their adsorption capacity.In this article, the kinds of MOFs materials were simply introduced.The adsorption performance of acidic, alkaline and neutral toxic gases by MOFs adsorption materials in gas masks were summarized, separately.Finally, the application prospect of MOFs materials as gas masks adsorption materials is outlooked.MOFs materials with wide range andhigh adsorption capacity used in the gas masks are ideal adsorption materials which are the focus of the adsorption materials in the future research.
