摘要
近年来,纳米阵列的结构以其尺寸均匀、结构有序、团聚较低以及与基底结合性良好等优点,在许多领域都被认为是一种先进、高效的催化剂。阵列化的金属有机框架(MOF)由于其三维结构和定向排列等方面的结构优势,使得MOF的性能得到最好的展现。在研究中,我们采用以Cu(OH)_2纳米棒阵列为牺牲模板与不同的有机配体反应得到三维的多层级的铜基金属有机框架阵列结构。我们使用不同的有机配体对该反应进行验证,均得到了相应的MOF阵列结构。由于其独特的阵列结构使得MOF的阵列表现出优越的催化性能,具有大的比表面积,稳定性及相关催化实验的选择性。这些工作对形成一种新的三维MOF结构和设计合成新型纳米催化剂有很重要的意义。
In recent years, nanoarrys with uniformed size, ordered structure, lower agglomeration and good connection with the substrate, have been proved as advanced and efficient catalysts in many areas. Metal-Organic Framework(MOF) will show the maximum performance in heterogeneous catalysis when they are sysnthesised intoimmobilized three-dimensional(3D) arrays. In this work, a coordination replication strategy is developed to construct copper-based MOF into 3D hierarchical nanoarray architectures using Cu(OH)_2 nanorod arrays as the sacrificial template. The Cu(OH)_2 nanorod arrays can serve as the Cu source which coordinates with organic ligand to form MOF crystals, as well as the 3D substrate to support the growth of Cu-based MOF. Due to the unique structural advantages(hierarchical porosity, large surface area and intimate contact with the 3D substrate), these MOF nanoarrays exhibit excellent catalytic activities and cycling stabilities in heterogeneous catalysis as functional structured catalysts. These results highlight the construction of 3D MOF structure and the application of nanoarrays catalysts.
