Abstract

Mesoporous Fe₃C is synthesised by combining a hard-templating approach with carbothermal reduction. The product shows high crystallinity, a transport pore size of d ≈ 20 nm and high specific surface area (415 m² g⁻¹). Its usefulness is exemplified by its catalytic activity and high stability in NH₃ decomposition.
