The electrocatalytic reduction of nitrate (ERN) to ammonia offers a promising route address energy shortages and environmental pollution, but its practical application is hindered by low selectivity due complex eight-electron transfer pathways high consumption (EC) from the kinetically sluggish oxygen evolution reaction (OER). This study proposes dual strategy: (1) designing multi-functional self-supported ANP electrode via vapor deposition enhance ERN activity (2) replacing OER with thermodynamically favorable anodic reactions (urea oxidation (UOR), sodium metabisulfite (S(IV)OR), sulfite urea (S(IV)/UOR)) reduce EC. cathode achieved removal rate (R%) 97.7%, (SE%) 91.8%, Faradaic efficiency (FE) 97.3% at −1.2 V, an yield 0.0616 mmol h−1 mg−1 EC 8.239 kWh/kg, while in situ-generated atomic hydrogen (*H) was identified as key improving selectivity. Replacing alternative significantly improved system efficiency: UOR reduced 17.5%, S(IV)OR saved 27.6% 7.1% higher yield, hybrid S(IV)/UOR 32.1% lower 12.6% greater than OER. These differences stemmed variations cell voltage production rates. work provides viable approach for selective nitrate-to-ammonia conversion guides design energy-efficient systems sustainable nitrogen recovery.

Bimetallic/multimetallic catalysts for nitrate reduction reaction (NO3-RR) have been extensively investigated benefiting from their synergistic effects in optimizing various intermediate adsorptions; however, the interphasic monometallic are often overlooked. Here we report an synergy between electron-rich Co(OH)2 and electron-deficient CoO, which asymmetric charge distribution cobalt-based heterojunction derived built-in electric field (BEF) significantly accelerates electron transfer lowers energy barriers NO3-RR. Theoretical calculations reveal that chemical affinities of Co atoms toward NO3- NO2- enhanced even adsorption switches to a spontaneous process. Simultaneously, BEF Co-based heterostructures greatly reduces barrier rate-determining step (*NO→*NOH) Therefore, resultant catalyst exhibits ampere-level NO3-RR performance, achieving record NH3 yield up 73.9 mg h-1 cm-2 at low potential -0.2 V with Faradaic efficiency (FE) 95.6%.

Abstract Catalyzed sodium borohydride (NaBH 4 ) hydrolysis is integral to H 2 ‐supply systems in fuel cells, with Co‐B among the most effective catalysts featured high B─H bond cleavage activity. However, its limited water dissociation capability produces an insufficient proton supply for generation. In this study, Ru element was introduced of deprotonation into system, constructing a dual‐site catalyst NaBH hydrolysis. A series situ characterizations confirmed accelerated kinetics on Ru@CoMoB. Electron transfer between Co and generated synergistic effect, simultaneously facilitating H─OH cleavage. Consequently, Ru@CoMoB exhibited remarkable catalytic performance, achieving hydrogen generation rate 26,936 mL g cat −1 min 10 wt% at room temperature—approximately 25 times higher than that CoMoB control (1,049 ). When implemented enabled stable operation 100 W cell.
