Abstract
Abstract Electrocatalytic nitrate reduction reaction (NO 3 RR) has been recognized as a sustainable route for nitrate removal and value‐added ammonia (NH 3 ) synthesis. Regulating the surface active hydrogen (*H) behavior is crucial but remains a formidable challenge, especially in neutral electrolytes, greatly limiting the highly selective NH 3 formation. Herein, we report the controlled synthesis of heterophase hcp/fcc non‐precious CuNi alloy nanostructures for efficient NH 3 electrosynthesis in neutral media. Significantly, hcp/fcc Cu 10 Ni 90 exhibits excellent performance with NH 3 Faradaic efficiency and yield rate of 98.1% and 57.4 mg h −1 mg cat −1 , respectively. In situ studies suggest that the high…
