Abstract

Electrochemical nitrate reduction to ammonia (NH₃) not only provides a promising strategy for green NH₃ synthesis, but also removes harmful nitrates from water. Herein, a Cu-doped FeP electrocatalyst was prepared for nitrate reduction, which achieved a high NH₃ faradaic efficiency of 92.5% and a high NH₃ yield of 0.787 mmol h^-1 cm^-2 in a neutral electrolyte, greatly surpassing its FeP counterpart.
