The　artificial　disturbance　in　the　nitrogen　cycle　has　necessitated　an　urgent　need　for　nitric　oxide　(NO)　removal.　Electrochemical　technologies　for　NO　conversion　have　gained　increasing　attention　in　recent　years.　This　comprehensive　review　presents　the　recent　advancements　in　selective　electrocatalytic　conversion　of　NO　to　high　value-added　chemicals,　with　specific　emphasis　on　catalyst　design,　electrolyte　composition,　mass　diffusion,　and　adsorption　energies　of　key　intermediate　species.　Furthermore,　the　review　explores　the　synergistic　electrochemical　co-electrolysis　of　NO　with　specific　carbon　source　molecules,　enabling　the　synthesis　of　a　range　of　valuable　chemicals　with　CN　bonds.　It　also　provides　in-depth　insights　into　the　intricate　reaction　pathways　and　underlying　mechanisms,　offering　valuable　perspectives　on　the　challenges　and　prospects　of　selective　NO　electrolysis.　By　advancing　comprehension　and　fostering　awareness　of　nitrogen　cycle　balance,　this　review　contributes　to　the　development　of　efficient　and　sustainable　electrocatalytic　systems　for　the　selective　synthesis　of　valuable　chemicals　from　NO.　The　artificially　induced　imbalance　in　the　nitrogen　cycle　necessitates　urgent　need　for　NO　removal.　This　review　highlights　recent　advances　in　selective　electrocatalytic　NO　conversion　into　valuable　chemicals,　emphasizing　catalyst　design,　electrolyte　composition,　mass　diffusion,　and　adsorption　energies.　It　elucidates　reaction　pathways　and　mechanisms,　providing　insights　into　the　challenges　and　prospects　of　NO　electrolysis　and　enhancing　awareness　of　the　nitrogen　cycle.　image
