Ammonia Synthesis Over an Iron Catalyst with an Inverse Structure (Adv. Sci. 11/2025)

Ammonia Synthesis Metallic iron particles loaded with aluminum hydride and K+ species, which is an inverse structure of a supported metal catalyst, surpass the ammonia synthesis activity per catalyst volume. Ammonia synthesis over the iron catalyst readily prepared from α-Fe2O3 was observed with a small apparent activation energy at 50 °C.
