“…The possibility to synthesize more complex amines by exploiting this key amine–aldehyde C–N coupling reaction was further demonstrated in our follow-up work . Ethylamine was successfully generated from NO 3 – -integrated CO 2 reduction catalyzed by a CuO-derived Cu electrocatalyst (Table ), which represented a 20-electron, 21-proton reduction cascade.…”

Given the limited product variety of electrocatalytic CO2 reduction reactions solely from CO2 and H2O as the reactants, it is desirable to expand the product scope by introducing additional reactants that provide elemental diversity. The integration of inorganic heteroatom-containing reactants into electrocatalytic CO2 reduction could, in principle, enable the sustainable synthesis of valuable products, such as organonitrogen compounds, which have widespread applications but typically rely on NH3 derived from the energy-intensive and fossil-fuel-dependent Haber–Bosch process for their industrial-scale production. In this Perspective, research progress toward building C–N bonds in N-integrated electrocatalytic CO2 reduction is highlighted, and the electrosyntheses of urea, acetamides, and amines are examined from the standpoints of reactivity, catalyst structure, and, most fundamentally, mechanism. Mechanistic discussions of C–N coupling in these advances are emphasized and critically evaluated, with the aim of directing future investigations on improving the product yield and broadening the product scope of N-integrated electrocatalytic CO2 reduction.

“…Formation of carbon-nitrogen bonds in the form of cyanide was revealed, which was never previously observed at room temperature in aqueous electrolyte. 28 We thus contribute to understanding of electrochemical C-N coupling reactions recently studied in the literature [29][30][31][32] . More importantly, we demonstrate that cyanide likely leads to formation of soluble Cu-C≡N complexes, which suggests a stable process for urea formation based on Cu electrodes might be di cult to achieve.…”

Recently, the efficient upgrading of abundant and cheap substances (H2O, CO2, N2, and NOxn) into valuable products by reduction and/or hydrogenation has attracted much attention. However, the traditional transformation processes of these oxidants generally suffer high‐energy input, complicated reactors, and rigorous reaction conditions due to their high thermodynamic stability and kinetic inertness. Recently, electrocatalytic reduction reactions (ERRs) for upgrading low‐grade substances have been perceived as promising for sustainable energy conversion due to the ambient condition, high selectivity, and atom economic feasibility. In this review, value‐added fuels and chemicals generation from low‐cost oxidants ERRs are systematically summarized. Specifically, H2 generation from ERR is introduced from water and seawater electrolysis; carbon‐containing compound generation from electrocatalytic COx reduction is classified into C1, and C2 and/or C2+ acquisition; valuable NH3 production is divided into nitrogen reduction reaction (NRR) and NOxn species reduction reaction (NOxnRR); and other valuable chemicals generation from multi‐substance reduction to CC bonds and CN bonds are also reviewed. This review aims to provide a comprehensive overview of high‐valued product generation from ERRs. Besides, an in‐depth understanding of such ERRs to valuable products has been presented, and current challenges and further prospects are also proposed.
