Ammonia (NH) plays a vital role in agriculture and chemical manufacturing, yet its conventional production is energy-intensive and environmentally harmful. Developing cleaner, more efficient alternatives is essential. Here we show a newly developed dual-metal nanocluster catalyst, FeCo/NC, that effectively converts nitrate and nitrite pollutants into NH through an electrochemical process. This catalyst achieves high NH production rates and Faradaic efficiency, surpassing single-metal Fe/NC and Co/NC catalysts, and remains stable over extended use. When incorporated into nitrate- or nitrite-based zinc batteries, the system enables simultaneous NH production and electricity generation, highlighting its potential for coupled energy recovery and environmental remediation. This work provides valuable design principles for bimetallic nanocluster catalysts and offers a promising strategy for the sustainable conversion of nitrogen-containing waste into useful chemicals.
氨（NH₃）在农业和化学制造中起着至关重要的作用，但其传统生产能源密集且对环境有害。开发更清洁、更高效的替代方法至关重要。在此，我们展示了一种新开发的双金属纳米团簇催化剂FeCo/NC，它能通过电化学过程有效地将硝酸盐和亚硝酸盐污染物转化为氨。这种催化剂实现了高氨产率和法拉第效率，超过了单金属Fe/NC和Co/NC催化剂，并且在长期使用中保持稳定。当集成到基于硝酸盐或亚硝酸盐的锌电池中时，该系统能够同时生产氨和发电，突出了其在耦合能量回收和环境修复方面的潜力。这项工作为双金属纳米团簇催化剂提供了有价值的设计原则，并为将含氮废物可持续转化为有用化学品提供了一种有前景的策略。
