Wastewater from industrial chemical synthesis, agricultural activities, and domestic sewage usually contains high levels of nitrogenous compounds, endangering environmental health human well-being. Nitrogenous wastewater electrolysis (NWE), despite its ecological merits, is inherently hampered by sluggish kinetics. To improve process efficiency, lower costs, avoid cross-contamination between the anode cathode, a range bifunctional transition-metal catalysts capable efficient operation at both electrodes have recently been developed. This review outlines progress in these for energy-saving production hydrogen wastewater, including urea, hydrazine, ammonia. It highlights their dual role degrading pollutants generating energy. The meticulously introduces key performance metrics NWE system surveys latest advancements catalysts, along with catalytic mechanisms. culminates detailed summary comparative analysis representative emphasizing electricity consumption efficiency. Lastly, existing challenges research prospects are thoroughly discussed.
