【摘要】：中空金属有机骨架材料MOFs因其具有高的比表面积、密度低、中空结构等优点受到人们广泛的关注,是近年来MOFs材料的一个重要研究方向。本文概括了中空结构MOFs(H-MOFs)制备方法的研究进展,重点介绍了聚苯乙烯牺牲剂和Cu_2O自我牺牲剂模板法、乳液型液-液和液-气界面的软模板法、Ostwald Ripening、Kirkendall效应等自组装方法的无模板法,并对其优缺点进行了讨论;探讨了中空MOFs在气体吸附和分离、催化方面的应用性能及在生物医药、磁性分离及环境保护方面的潜在应用;并提出今后H_MOFs研究的主要方向是合成新型H_MOFs、制备形貌多样、结晶性能好的新型高稳定性材料、精确控制壳层厚度以及开发新的H_MOFs制备方法。
[Abstract]:Hollow metal-organic framework material (MOFs) has attracted much attention because of its high specific surface area, low density and hollow structure. It is an important research direction of MOFs materials in recent years. In this paper, the progress in the preparation of hollow structure MOFsN H-MOFs is summarized. The template free method for self-assembly of polystyrene sacrificial agent and Cu_2O self-sacrificial agent template, the soft template method of emulsion liquid-liquid and liquid-gas interface and the Ostwald Ripeningn Kirkendall effect are introduced. The advantages and disadvantages of hollow MOFs in gas adsorption and separation, catalysis and potential applications in biomedicine, magnetic separation and environmental protection were discussed. The main research direction of H_MOFs in the future is to synthesize new HMOFs, to prepare new high stability materials with various morphology and good crystallization performance, to control the shell thickness accurately and to develop a new preparation method of H_MOFs.
