摘要 The electrocatalytic nitrogen oxidation reaction (NOR) represents an environmentally friendly alternative to the energy-intensive industrial synthesis of nitrate, traditionally derived from ammonia produced via the Haber–Bosch process. The primary challenges in electrocatalytic NOR revolve around the effective activation of inert nitrogen and achieving a suitable oxygen evolution reaction (OER). To address these challenges, the development of advanced electrocatalysts capable of efficiently adsorbing and activating nitrogen while simultaneously modulating the OER activity is paramount for advancing electrochemical NOR technologies. This work innovatively integrated Ru clusters with Mn-doped RuO2, balancing NOR and OER through interfacial electron transfer at Ru/Mnx-RuO2 grain boundaries. The incorporation of Mn into RuO2 elevated the OER reaction energy to 0.630 eV, compared to 0.568 eV for pristine RuO2, while simultaneously enhancing nitrogen adsorption and activation on the Ru clusters. This synergistic effect resulted in an optimized NOR performance. The engineered Ru/Mn1.04-RuO2 exhibited positive catalytic efficiency for NOR, achieving a record-high nitrate yield of 52.6 μg mg–1 h–1 and a Faraday efficiency of 44.29% under alkaline conditions, demonstrating significant progress toward viable electrochemical nitrate production.
