缺陷化金属-有机框架在催化领域的应用进展

Progress in the application of defective metal-organic frameworks in catalysis

缺陷化金属-有机框架(DMOFs)是一类具有缺陷结构的金属-有机框架材料。由于具有比表面积大、孔隙率高、不饱和金属配位点以及功能结构多样性,DMOFs在催化领域展示出广泛的应用前景。简要介绍了DMOFs缺陷结构的种类和性质以及合成方法,并从热催化、光催化和电催化三方面对DMOFs在催化领域中的应用展开讨论,重点阐述了结构缺陷和催化性能之间的关系。最后,对该领域存在的问题和未来的机遇进行了总结与展望。

Defective metal-organic frameworks(DMOFs)are a class of metal-organic framework materials with structural imperfections.Due to the large surface area,high porosity,unsaturated metal coordination sites,and diverse structural functionality,DMOFs have shown great potential in the field of catalysis.This article provided a brief introduction to the types and properties of DMOF defects as well as the synthetic methods.Then the application of DMOFs in catalysis was reviewed from three perspectives:thermal catalysis,photocatalysis,and electrocatalysis,focusing on the relationship between structural defects and catalytic performance.Finally,the existing challenges and future opportunities in this field were put forward.
