Abstract
Abstract Improving the selective ammonia production capacity of electrocatalytic nitrate reduction reaction (NO 3 RR) at ambient conditions is critical to the future development and industrial application of electrosynthesis of ammonia. However, the reaction involves multi‐proton and electron transfer as well as the desorption and underutilization of intermediates, posing a challenge to the selectivity of NO 3 RR. Here the electrodeposition site of Co is modulated by depositing Bi at the bottom of the catalyst, thus obtaining the Co+Bi@Cu NW catalyst with a Bi‐Co corridor structure. In 50 m m NO 3 − , Co+Bi@Cu NW exhibits a highest Faraday efficiency of ≈100% (99.51%), an ammonia yield rate of 1858.2 µg h −1…
