Abstract:

CO2 is the main greenhouse gas and an important C1 resource. C—N bonds formation plays an important role in chemical industry, biosynthesis and medicine. In recent years, with the deepening of carbon neutrality and green chemistry concept, the strategy of electrochemical C—N bonds construction has attracted much attention due to its advantages of environmental benign, low carbon, simplicity and green. At the same time, continuous consumption of fossil resource results in a series of environmental and resource problems, and the green sustainable synthesis of important chemicals and fuels is attracting increasing attention. This paper focuses on the research progress of CO2-involved electrochemical C—N formation to prepare important chemicals. The electrochemical synthesis of urea, amide and amine are reviewed from the perspectives of catalytic system construction, reaction processes, and reaction mechanism. Finally, the critical challenges remaining in this research area and promising directions for future research are discussed.

Key words: CO2 Reduction, Electrocatalysis, C—N coupling, Green chemistry
