Electrocatalytic urea formation most commonly involves the co-reduction of NOx species with CO2. This limits overall energy efficiency as commodity-scale NOx is produced from N2 via NH3. The swings in nitrogen oxidation state can be minimized through direct oxidative electrocatalytic reaction of CO and NH3 to urea, as shown in this study.
