Transformation of CO2 based on metal-organic framework (MOF) catalysts is becoming a hot research topic, not only because it will help to reduce greenhouse gas emission, but also because it will allow for the production of valuable chemicals. In addition, a large number of impressive products have been synthesized by utilizing CO2 . In fact, it is the formation of new covalent bonds between CO2 and substrate molecules that successfully result in CO2 solidly inserting into the products, and only four types of new CX bonds, including CH, CC, CN, and CO bonds, are observed in this exploration. An overview of recent progress in constructing CX bonds for CO2 conversion catalyzed by various MOF catalysts is provided. The catalytic mechanism of generating different CX bonds is further discussed according to both structural features of MOFs and the interactions among CO2 , substrates, as well as MOFs. The future opportunities and challenges in this field are also tentatively covered.

金属有机骨架催化CO 2化学固定中CX键的形成。

基于金属有机框架（MOF）催化剂的CO2转化正成为一个热门研究课题，不仅因为它有助于减少温室气体排放，而且还因为它可以生产有价值的化学物质。另外，利用二氧化碳已经合成了许多令人印象深刻的产品。实际上，正是CO2与底物分子之间新的共价键的形成成功地导致了CO2牢固地插入产品中，并且只有四种新型的CX键，包括CH，CC，CN在此勘探中观察到，以及CO键。本文概述了在各种MOF催化剂的催化下建立CX键进行CO2转化的最新进展。根据MOF的结构特征以及CO 2，底物以及MOF之间的相互作用，进一步讨论了产生不同CX键的催化机理。该领域的未来机遇和挑战也被初步涵盖。
