Catalytic Ammonia Formation with Electrochemically Reduced Samarium Diiodide from Samarium Triiodide and Water from Dinitrogen

Ammonia was catalytically formed from dinitrogen using samarium diiodide (SmI2), which was electrochemically reduced from samarium triiodide (SmI3) as a reductant and water as a proton source. The process was assessed as a model reaction for the electrochemical reduction of dinitrogen to ammonia under ambient reaction conditions. In this reaction system, electrochemical energy could be converted to chemical energy through ammonia using samarium iodide with high Faradaic efficiency.
