Copper-based catalysts have been widely used in the field of nitrate reduction reaction (NO3RR) to ammonia, demonstrating high rates. However, their low selectivity for ammonia production poses significant limitations practical applications. In this study, we present that incorporation Ru into Cu@Ni foam can achieve nearly 100% NH3 and a faradaic efficiency 96.8% NO3RR. not only facilitates generation adsorbed hydrogen but also suppresses HER reaction. This be attributed unique electron distribution exhibited by atoms when surrounded Cu, leading decreased electron-accepting capability. Consequently, results diminished Lewis acidity H* adsorption. Importantly, it was confirmed Cu with serves as "anchor" atomic generated from Ru, inhibiting ensuring availability subsequent production. The synergistic effect between enhanced NH3. Remarkably, substituting oxygen evolution (OER) coupled anodic oxidation benzyl alcohol benzaldehyde significantly accelerate rate 1.7 times achieves 90% conversion rate. research introduces innovative strategies designing high-performance ammonia-selective electrocatalysts highlights potential industrial applications synthesis high-value products.
