Electrocatalytic　C-N　coupling　reaction　is　regarded　as　a　promising　strategy　for　achieving　clean　and　sustainable　urea　production　by　coreducing　CO2　and　nitrogen　species,　thus　contributing　to　carbon　neutrality　and　the　artificial　nitrogen　cycle.　However,　restricted　by　the　sluggish　adsorption　of　reactants,　competitive　side　reactions,　and　multistep　reaction　pathways,　the　electrochemical　urea　production　suffers　from　a　low　urea　yield　rate　and　low　selectivity　so　far.　In　order　to　comprehensively　improve　urea　synthesis　performance,　it　is　crucial　to　develop　highly　efficient　catalysts　for　electrochemical　C-N　coupling.　In　this　article,　the　catalyst-designing　strategies,　C-N　coupling　mechanisms,　and　fundamental　research　methods　are　reviewed.　For　the　coreduction　of　CO2　and　different　nitrogen　species,　several　prevailing　reaction　mechanisms　are　discussed.　With　the　aim　of　establishing　the　standard　research　system,　the　fundamentals　of　electrocatalytic　urea　synthesis　research　are　introduced.　The　most　important　catalyst-designing　strategies　for　boosting　the　electrocatalytic　urea　production　are　discussed,　including　heteroatom　doping,　vacancy　engineering,　crystal　facet　regulation,　atom-scale　modulation,　alloying　and　heterostructure　construction.　Finally,　the　challenges　and　perspectives　are　proposed　for　future　industrial　applications　of　electrochemical　urea　production　by　C-N　coupling.　©　2024　Wiley-VCH　GmbH.
