Metal-organic frameworks (MOFs), as a new stable class of hybrid materials synthesized, regulated and decorated by rational incorporating organic bridging ligands and metal ions with well-defined coordination geometry have become promising candidates for heterogeneous catalysis in industrial applications. Compared with homogeneous catalysts, MOF catalysts can be easily recycled and reused for several times; while compared with traditional heterogeneous catalysts, they possess tunable size and catalytic centers via exchange or modification of their components. This review will sketch typical successful MOF-catalyzed reactions and summarize various catalytic centers, including the open metal sites, bifunctional acid-base sites in MOFs, as well as catalytic centers introduced to MOFs via PSM. The periodic order and site isolation of the catalytic struts in MOFs eliminate the multimolecular catalyst deactivation pathways to extend the catalytic centers’ functional lifetime and facilitate the studies of their activities and reaction mechanisms. Furthermore, detailed discussion on how the catalytic centers play the roles in the catalytic reactions and how to control the activity and selectivity of them will be given via typical reported examples.

具有催化中心的金属有机骨架:从合成到催化应用

金属有机骨架(MOFs)作为一种新的稳定的杂化材料类别,通过合理地结合有机桥联配体和具有明确配位几何形状的金属离子来合成,调控和修饰,已成为工业应用中多相催化的有希望的候选者。与均相催化剂相比,MOF催化剂可轻松回收利用多次。与传统的非均相催化剂相比,它们具有可调整的大小和通过交换或修饰其组分而形成的催化中心。这篇综述将概述成功的典型MOF催化反应,并总结各种催化中心,包括MOF中的开放金属位点,双官能酸碱位以及通过PSM引入MOF的催化中心。MOF中催化支柱的周期性有序和部位隔离消除了多分子催化剂的失活途径,从而延长了催化中心的功能寿命,并促进了其活性和反应机理的研究。此外,将通过典型的报道实例详细讨论催化中心如何在催化反应中发挥作用以及如何控制它们的活性和选择性。
