Isolated Copper Atoms Boost *NO 3 Adsorption and Active Hydrogen Retention over Zinc Oxide for Ammonia Electrosynthesis at Ampere-Level Current Densities

The use of renewable electricity to drive the electroreduction of nitrate to ammonia can simultaneously achieve the green synthesis of ammonia and alleviate the environmental pollution of nitrate. However, the industrial requirement for ammonia synthesis with ampere-level current densities remains a grand challenge. In addition, the electroreduction of nitrate to ammonia reaction requires multiple steps of deoxygenation and hydrogenation of *NO3 intermediates. Therefore, it is urgent to clarify the relationship between the adsorption strength of *NO3/*H (active hydrogen) intermediates and the catalytic activity. Herein, we achieved highly selective ammonia electrosynthesis at ampere-level current densities by…
