摘要:

金属-有机框架材料(MOFs)由于其巨大的比表面积、高孔隙率、有序的孔隙结构及优异的稳定性等特点,在诸多领域得到了广泛研究,其中在吸附/分离领域,特别是吸附水体中的合成染料方面展现出良好的应用前景。本文介绍了常见的MOFs作为多孔吸附材料的结构设计方法,重点分析了金属离子和配体的交换、有机配体的功能化修饰对MOFs的晶体结构、比表面积、孔容的影响,探讨了MOFs的结构设计与其吸附性能的关系,并探究MOFs对阳离子染料和阴离子染料的吸附机理,以此为基础,分析了MOFs对亚甲基蓝、罗丹明B等阳离子染料和刚果红、铬黑T等阴离子染料的吸附性能,最后总结了MOFs多孔吸附材料的技术优势及目前存在的问题,展望未来发展方向,以期对MOFs在合成染料高性能吸附领域的发展提高参考。

Abstract:

Metal-organic framework materials (MOFs) have been extensively studied in many fields due to their huge specific surface area, high porosity, ordered pore structure and excellent stability, among which they show good application prospects in the field of adsorption/separation, especially in the adsorption of synthetic dyes in aqueous humor. The structural design methods of common MOFs as porous adsorbent materials are introduced. The effects of exchange of metal ions and ligands, functionalized modification of organic ligands on the crystal structure, specific surface area and pore capacity of MOFs are analyzed with emphasis, and the relationship between the structural design of MOFs and their adsorption performance is investigated. And then, the adsorption mechanism of MOFs on cationic dyes and anionic dyes is investigated. Plus, the adsorption properties of MOFs on cationic dyes such as Methylene blue and Rhodamine B, and anionic dyes such as Congo red and Chromium black T are analyzed on this base. Finally, the technical advantages and current problems of MOFs porous adsorption materials are summarized, and the future development direction is prospected in order to improve the reference of MOFs for the development in the field of high-performance adsorption.
