Abstract The electrochemical nitrate reduction reaction (NO 3 RR), which converts harmful nitrates into valuable ammonia (NH ) with zero carbon emission, is one of the most promising alternatives to Haber–Bosch process. However, NO RR process complex and involves multiple proton‐coupled electron transfers that generate intermediates or byproducts, such as 2 − , resulting in low yields faradaic efficiency (FE). Herein, by constructing a FeCu bimetallic catalyst (FeCu‐NC), hydrogenation position *NO switched at dual‐atom site, preventing desorption intermediate. Furthermore, transfer from Cu Fe sites mimics flow direction natural nitrite reductase enzymes accelerates NH achieving efficient conversion . A 24‐hour electrocatalytic experiment FeCu‐NC demonstrates negligible formation throughout process, an production rate 6.13 mg h −1 cat impressive FE 95%, are remarkably superior comparison electrocatalysts. This work opens new avenues for fundamental understanding catalytic mechanisms development next‐generation catalysts sustainable production.
