Abstract
In the agroindustry, urea (NH2CONH2) is of great importance as a nitrogen-rich fertilizer. Urea synthesis is conventionally operated at high pressure and high temperature by the mixture of CO2 with NH3. Ammonia is produced from high purity N2 and H2 gases at high temperatures and pressures via the HaberBosch process. Electrocatalytic N2 reduction to ammonia is an attractive alternative th…
