摘要：

A series of ordered mesoporous Fe-MC-x nanocomposites were facilely synthesized via an evaporation induced self-assembly strategy. The Fe nanoparticles (NPs) were highly dispersed and embedded in mesoporous carbon channels, and their particle sizes (mean size = 8, 12 and 16 nm) were well tuned with the aid of acetylacetone chelating agent. Catalytic ammonia decomposition to COx-free hydrogen was used to evaluate their catalytic performances. It was found that the prepared Fe-MC-x nanocomposites showed an obvious size-dependent activity. Owing to confinement and size effect, the Fe-MC-x nanocomposites with the smallest Fe NPs showed the highest ammonia decomposition activity, giving a nearly 72% NH3 conversion and 16.24 mol g(Fe)(-1) h(-1) at 600 degrees C under a GHSV = 6000 h(-1).
