Abstract Oxide‐derived copper (OD‐Cu) has exhibited significant promise in nitrate electroreduction reaction (NO 3 RR) due to their hybrid Cu oxide states (Cu δ+ ) for stabilizing key intermediates. However, owing the intrinsic vulnerability of reduction during NO RR, it is still challenging develop highly active and durable OD‐Cu catalysts. Herein, a unique strategy reported stabilize + state by dynamically introducing metallic Ag clusters oxidized CuAgO x nanosheets form heterostructure 0 ‐CuAgO . Operando X‐ray absorption spectroscopy diffuse reflection infrared Fourier transform reveal strong correlation between NH production content , with peak performance achieved when maximized. acts as an electron acceptor, preventing over‐reduction RR.
