Abstract Electrocatalytic conversion of nitrates and carbon dioxide to urea under ambient conditions shows promise as a potential substitute for traditional synthesis processes characterized by high consumption pollution. In this study, straightforward one‐pot method is employed prepare highly efficient FeNC‐Fe 1 N 4 electrocatalyst, consisting atomically dispersed Fe sites metallic clusters (FeNC) with particle size 4–7 nm. The catalyst exhibits remarkable electrocatalytic activity from nitrate anion (NO 3 − ) (CO 2 ), achieving production rate 38.2 mmol g cat −1 h at −0.9 V (vs RHE) Faradaic efficiency 66.5% −0.6 RHE). Both experimental theoretical results conclusively demonstrate that species provide active the adsorption activation NO CO , respectively, synergistic effect between significantly enhances electrochemical synthesis. all, work contributes rational design comprehensive dual‐active site iron‐based facilitating sustainable

Abstract Electrochemical C–C and C–N coupling reactions with the conversion of abundant inexpensive small molecules, such as CO 2 nitrogen‐containing species, are considered a promising route for increasing value reduction products. The development high‐performance catalysts is key to both electrocatalytic reactions. In this review, we present systematic summary reaction systems reduction, along mechanisms bonds over outstanding materials recently developed. intermediate species pathways related well catalyst‐structure relationship will be also discussed, aiming provide insights guidance designing efficient systems.
