Cu‐Co Dual Sites Tandem Synergistic Effect Boosting Neutral Low Concentration Nitrate Electroreduction to Ammonia

Abstract Electrochemical nitrate reduction reaction (NO 3 − RR) has emerged as an alternative strategy for wastewater treatment and ammonia production in neutral low‐concentration nitrate. However, the electrocatalyst faces the challenge of limited NO 3 − distribution and deficient active hydrogen (H ads ) on the catalyst surface resulting from the low concentration of NO 3 − and the difficulty of water splitting under neutral conditions. Here, a Cu‐Co dual sites tandem synergistic catalysis mechanism has been proposed by doping Cu into CoP to facilitate the adsorption and conversion of NO 3 − on Cu and to accelerate the water splitting on CoP leading to the significantly high NO 3 − RR performance. The…
