Carbon neutrality is one of the central topics of not only the scientific community but also the majority of human society. The development of highly efficient carbon dioxide (CO2) capture and utilization (CCU) techniques is expected to stimulate routes and concepts to go beyond fossil fuels and provide more economic benefits for a carbon-neutral economy. While various single-carbon (C1) and multi-carbon (C2+) products have been selectively produced to date, the scope of CCU can be further expanded to more valuable chemicals beyond simple carbon species by integration of nitrogenous reactants into CO2 reduction. In this Review, research progress toward sustainable production of high-value-added chemicals (urea, methylamine, ethylamine, formamide, acetamide, and glycine) from catalytic coupling of CO2 and nitrogenous small molecules (NH3, N2, NO3 –, and NO2 –) is highlighted. C–N bond formation is a key mechanistic step in N-integrated CO2 reduction, so we focus on the possible pathways of C–N coupling starting from the CO2 reduction and nitrogenous small molecules reduction processes as well as the catalytic attributes that enable the C–N coupling. We also propose research directions and prospects in the field, aiming to inspire future investigations and achieve comprehensive improvement of the performance and product scope of C–N coupling systems.

“…And V 2 N 6 C could inhibit the HER side reaction and accordingly improve the urea selectivity due to its weak hydrogen bonding. Su and coauthors theoretically investigated a global-minimum conductive and stable CuB 12 planar monolayer with the best catalytic activity for urea production among all the reported electrocatalysts in the view of thermodynamics and kinetics . The unit cell of CuB 12 planar monolayer (space group of P 4/ MMM ) exhibited a square shape with one Cu atom and 12 B atoms and an optimal lattice constant of 6.18 Å (Figure c).…”

The authors proposed several possible reaction mechanisms for urea electrosynthesis by the simultaneous reduction of CO 2 /N 2 molecules, such as the CO 2 , OCOH, CO, NCON, and mixed pathways (Figure 10d).…”

Industrial urea synthesis is performed under harsh conditions requiring huge energy consumption and accompanied by heavy environmental pollution. Electrocatalytic C− N coupling for valuable urea synthesis from the coreduction of CO 2 and an inexpensive nitrogen source, such as N 2 , nitrite, nitrate, and NO, under ambient conditions is a potential green and sustainable substitute for the harsh industrial process. However, the nuts and bolts of electrocatalytic urea synthesis are seldom systemically reviewed. In this Perspective, theoretical and experimental research progress toward urea electrosynthesis is introduced and critically highlighted. From the view of the reaction pathway for the generation of urea molecules, chemiadsorption and activation of inert molecules (CO 2 or N 2 ) and the subsequent C−N couplings are the most important steps to determine the efficiency and selectivity of electrocatalytic reactions. The mechanisms of C−N coupling and hydrogenation toward urea formation in the above progress are summarized and rigorously estimated. This perspective reviews the exploration and preparation of electrocatalysts for urea synthesis with high efficiency and selectivity.
