Abstract

We report on an unconventional and highly active iron catalyst embedded within molten barium amide (Ba(NH₂)₂) for NH₃ decomposition. A ternary barium iron amide (Ba–NH_x–Fe) species plays a crucial role in NH₃ decomposition catalysis. The synergy among multiple Fe atoms, Ba atoms, and the NH₂ moiety is responsible for its high catalytic activity under low temperatures.
