Abstract: Uniform and highly dispersed [gamma]-[Fe.sub.2][O.sub.3] nanoparticles supported on CMK-5 carbons and C/SBA-15 composites are prepared by simple impregnation and thermal treatment. [gamma]-[Fe.sub.2][O.sub.3] nanparticles are fully immobilized within the channels of the supports because of the confinement effect and they have showed the highest ammonia decomposition activity of Fe-based catalysts in the reaction.
