Embedded Fe-Cu Pairs Enable Tandem Nitrate-to-Ammonia Electroreduction.

ABSTRACT: Electrochemical nitrate reduction (e-NO₃RR) to ammonia (NH₃) represents a transformative technology that seamlessly integrates environmental remediation with resource regeneration. This approach is crucial for restoring equilibrium in the global nitrogen cycling, advancing green chemistry, and accelerating the transition toward a sustainable circular economy. However, under pH-neutral conditions, the simultaneous occurrence of two competing reactions (Hydrogen Evolution Reaction and NO₃RR) at the same active sites results in considerable interference, significantly limiting the catalytic efficiency and selectivity. Here a Fe-Cu pair (Cu-N₃/Fe₃-N₈) electrocatalyst is meticulously designed, achieving a NH₃ productio
