Gas–Water Interfacial Conversion of CO2-Derived Carbamates to Substituted Ureas

Abstract Amines (RNH2) capture carbon dioxide (CO2) in water as carbamates (RNHCO2–), one C–N bond short of a urea (RNHCONHR′). Interfacial studies have so far produced only unsubstituted urea from inorganic nitrogen sources, whereas conversion of organic carbamates to substitute...

Contact-Electro-Catalysis Enables Ambient Coupling of CO2 and NH3 for Urea

Abstract Urea is an essential chemical for agriculture and industry, yet its production remains dominated by energy-intensive thermochemical processes. Here we report a contact-electro-catalysis (CEC) strategy that enables direct urea synthesis from carbon dioxide and aqueous amm...
