5th GXI Seminar in 2023 "Hydrogen production and utilization from renewable energy -Development of anion exchange membrane water electrolysis and polymer electrolyte fuel cells"

The development of a new catalyst for synthesizing ammonia from hydrogen and nitrogen at temperatures below 50 ºC was reported. The catalyst is a composite material of calcium fluorohydride (CaFH), a substance in which hydrogen and fluorine are bonded to abundant calcium, and ruthenium (Ru) nanoparticles, and can synthesize ammonia from hydrogen and nitrogen at room temperature. We focused on the fact that CaFH has a strong ability to impart electrons at low temperatures and linked this science to the development of a catalyst for the synthesis of ammonia at low temperatures. The catalyst is expected not only to significantly improve the efficiency of ammonia production, but also to lead to zero CO2 emissions, a greenhouse gas, using natural energy.
