Highly-loaded and well-dispersed Fe 5 C 2 nanoparticles within ordered mesoporous carbon CMK-3 (Fe 5 C 2 @CMK-3) were prepared via a simple melt infiltration method. They were successfully applied to high-temperature Fischer-Tropsch synthesis, and showed high CO conversion (91%) and activity (5.1 × 10 −4 mol co g Fe −1 s −1 ) as well as good selectivity (38 wt%) for gasoline-range hydrocarbons (C 5 –C 12 ). The catalytic property of Fe 5 C 2 @CMK-3 was newly interpreted, based on theoretical data obtained by computational simulations.
