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。
H_MOFs have attracted considerable interest and found potential applications in many fields due to their special properties such as high surface area, low density and hollow structure, and the related reseach has been an important direction of MOFs materials. This article mainly featured recent research progress towards various preparation methods of H MOFs, with the focus on the hard-template routes including polystyrene and CUE0, the soft-template routes including emulsion-based interracial synthesis and gas-liquid interracial, and the template-free routes including Ostwald Ripening and Kirkendall effect were analyzed in detail. And the advantages and disadvantages of these methods, were discussed respectively. Applications of H_MOFs in gas adsorption and separation, catalysis, and potential applications of H_MOFs in biomedical, magnetic separation and environment protection were also discussed. The preparation of novel and highly stable H_MOFs materials with versatile morphology and good crystallinity, the precise control of shell thickness and the development of preparation methods of H_MOFs were proposed as the main future research and development directions of H MOFs.
