Active hydrogen boosts electrochemical nitrate reduction to ammonia
Nature Communications, 2022 Electrochemical nitrate reduction to ammonia is a promising alternative strategy to the traditional Haber-Bosch process but suffers from a low Faradaic efficiency and limited ammonia yield due to the sluggish multi-electron/proton-involved steps. Herein,
