Pulsed Nitrate-to-Ammonia Electroreduction Facilitated by Tandem Catalysis of Nitrite Intermediates

Panpan Li et al.

Summary: Electroreduction of nitrate to ammonia provides a promising approach for nutrient recycling and recovery from wastewater while ensuring energy and environmental sustainability. By utilizing a pulse electrolysis strategy and a Cu single-atom gel (Cu SAG) catalyst, ammonia production from nitrate and nitrite under neutral conditions is achieved with significantly enhanced Faradaic efficiency and yield rate compared to constant potential electrolysis. This work highlights the synergistic effect of pulse electrolysis and Cu SAGs with three-dimensional framework structures for efficient conversion of nitrate to ammonia through tandem catalysis of unfavorable intermediates.
