 The study proposes replacing copper with ferrous iron and layered double hydroxide catalysts to boost nitrogen reduction reaction activity. Achieving A and H3 yield rate of 33.1 plus or minus 2.5 gh-1 cat, minus 1 and a desirable faradaic efficiency, FE. Of 21.7 plus or minus 1.8% in a neutral electrolyte of 0.1 MNA2SO4, outperforming the CU, 2, FE, 3, LDH catalyst without FE, 2. Ferrous iron adjusts the D-band center position to improve and to adsorption and reduces the energy barrier of the potential determining step, PDS, to facilitate the NRA process.
