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,

Electrochemical ammonia synthesis via nitrate reduction on Fe single atom catalyst
Nature Communications, 2021 Electrochemically converting nitrate, a widespread water pollutant, back to valuable ammonia is a green and delocalized route for ammonia synthesis, and can be an appealing and supplementary alternative to the Haber-Bosch process.
