摘　　要：MOFs核壳结构材料是近十几年来化工材料领域的研究热点,其中MOFs可作核,亦可作壳。本文从不同的核出发综述了以MOFs为壳的核壳结构材料的合成方法,如外延生长法、后合成修饰法等;概述了其展现出优于核层与壳层的特性(如选择性分离、催化性、磁性等)及以MOFs为壳的核壳结构材料在气体吸附、催化剂、磁性分离等应用上的研究,这给MOFs复合材料的产业化带来很大的潜力;而内核主要包括单质金属及非金属类内核、氧化物类内核、MOFs类内核;最后对MOFs为壳的核壳结构复合材料合成方法的改进和拓展、结构均一稳定、多功能化的发展作了展望。Core-shell-structure MOFs materials became a hot spot in the field of chemical and materials over the last decade, and MOFs can act as core or shell. This paper mainly reviews the synthesis methods of core-shell-structure material with MOFs as shell according to different nuclear types,such as epitaxial growth method,and post-synthetic modifications; and summarizes the performances which are better than single core or shell,such as separation selectivity,catalysis,magnetic performance,and the development of the core-shell-structure materials with MOFs as shell in gas adsorption,catalysts,magnetic separation,which bring a large potential for MOFs composite industrialization. The cores include metallic and non-metallic element core, oxides core, and MOFs core. And the core-shell-structure composites with MOFs as shell are prospected for the improvement and development of synthesis methods in order to obtain uniform and stable structure and multi-function.
