Electrified Conversion of Contaminated Water to Value: Selective Conversion of Aqueous Nitrate to Ammonia in a Polymer Electrolyte Membrane Cell

The Cover Feature shows how nitrates, often considered as pollutant and waste species, can be efficiently converted to valuable ammonia in a polymer electrolyte membrane electrolysis cell. By using ruthenium-based catalyst controlling proton transport through the membrane, competing hydrogen evolution reaction was successfully suppressed, enabling high faradaic efficiency for production.
