Abstract
Abstract Harnessing renewable electricity to transform abundant environmental resources into fertilizers is central to sustainable development. Electrochemical nitrate‐to‐ammonia conversion provides a promising route, yet its efficiency is constrained by the elusive surface hydrogenation dynamics governing multi‐step *NO x reduction. Here, a cooperative descriptor (Ψ) derived from large‐language‐models‐assisted mining and energetic analysis successfully identifies NiCu single‐atom alloys (SAAs) as optimal catalysts. Pulse electrodeposition delivers atomically dispersed alloys with tunable structures, achieving a maximum Faradaic efficiency (FE) of ∼95% and yield rate (YR) of ∼11.4 mg h −1 cm −2 . In situ…
