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

ABSTRACT: Electrochemical nitrate reduction reaction (NO₃ ^-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 NO₃ ^- distribution and deficient active hydrogen (H_ads) on the catalyst surface resulting from the low concentration of NO₃ ^- 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 NO₃ ^- on Cu and to accelerate the water splitting on CoP leading to the significantly high NO₃ ^-RR p
