Thermocatalytic Conversion of CO2 to Valuable Products Activated by Noble‐Metal‐Free Metal‐Organic Frameworks

Thermocatalysis of CO2 into high valuable products is an efficient and green method for mitigating global warming and other environmental problems, of which Noble‐metal‐free metal–organic frameworks (MOFs) are one of the most promising heterogeneous catalysts for CO2 thermocatalysis, and many excellent researches have been published. Hence, this review focuses on the valuable products obtained from various CO2 conversion reactions catalyzed by noble‐metal‐free MOFs, such as cyclic carbonates, oxazolidinones, carboxylic acids, N‐phenylformamide, methanol, ethanol, and methane. We classified these published references according to the types of products, and analyzed the methods for improving the catalytic efficiency of MOFs in CO2 reaction. The advantages of using noble‐metal‐free MOF catalysts for CO2 conversion were also discussed along the text. This review concludes with future perspectives on the challenges to be addressed and potential research directions. We believe that this review will be helpful to readers and attract more scientists to join the topic of CO2 conversion. Constructing efficient catalysts for thermocatalysis of CO2 to valuable products has attracted wide attention, and noble‐metal‐free metal–organic frameworks (MOFs) have become promising candidates owing to high efficiency and low cost. This review discusses CO2 conversion catalysed by noble‐metal‐free MOFs, such as conversion of CO2 to benzimidazoles, N‐formamides, carboxylic acids, carbonic esters, or oxazolidinones.
