Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

open access: yesAdvanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...
