GREEN AMMONIA UPDATE: Aiming to bypass the nitrate to ammonium reduction reaction we demonstrate a NOx to ammonia path, which requires less electrons but also allows a gas to gas conversion with air to gaseous ammonia. 👇 doi.org/10.1002/anie.2025082…

Regulating Multifunctional Oxygen Vacancies for Plasma‐Driven Air‐to‐Ammonia Conversion

High defective Fe2O3 nanoparticles on Cu synthesis by plasma introduced multifunctional oxygen vacancies achieving 100% NH3 selectivity through a plasma-electrochemical system capable of directly...

Shipping nitrogen fertilizer around the globe makes little sense and generating CO2 emissions to create it makes even less sense! The solution? air, water and electrons. Follow our scaleup of sustainable, locally produced nitrogen fertilizers. #sustainability #ammonia #netzero
