摘　　要：锆基金属-有机骨架材料(Zr-MOFs)具有优异的结构稳定性、高比表面积和孔道易于功能化等特点,被广泛应用于异相催化领域。从MOFs结构组成出发,简述了构建具有催化功能Zr-MOFs的4种策略,即构建不饱和Zr-Oxo节点、骨架侧链嫁接催化基团、后修饰法构筑催化基团和孔道负载客体活性物。讨论了不同位点构筑Zr-MOFs催化剂的优缺点,详细介绍了Zr-MOFs在有机催化反应中的应用。最后提出了Zr-MOFs催化剂面临的挑战及解决方案,以及对其进一步发展做出了展望。Zr-based metal-organic frameworks(Zr-MOFs)have been intensively studied in heterogeneous catalysis owing to their excellent structural stability,high surface areas,and functional pore structures.In this review,we have briefly summarized four different strategies for the construction of catalytic active Zr-MOFs based on their structures and components,that is,unsaturated Zr-Oxo nodes,catalytic groups grafted on the backbone of MOFs,post-synthetic modification,and encapsulation of functional guests.The advantage and disadvantage of the above strategies are discussed,and examples of Zr-MOFs for organic catalysis are detailed.Finally,the challenges and solutions,as well as the further developments of Zr-MOFs catalysts are discussed.
