Efforts to electrochemically produce ammonia have mainly focused on dinitrogen as a feedstock. Now, an electrocatalyst composed of Cu embedded in an organic molecular solid is designed, which efficiently and selectively converts nitrate ions to ammonia, paving a way to nutrient recovery and recycling.
