Hyperactive iron carbide@N-doped reduced graphene oxide/carbon nanotube hybrid architecture for rapid CO hydrogenation

A hierarchical architecture designated as Fe 5 C 2 @Ns-rGO/CNT, consisting of carbon nanotubes, steam activated N-doped reduced graphene oxides, and activated iron carbide nanoparticles, was prepared via microwave irradiation and subsequent CO activation. The Fe 5 C 2 @Ns-rGO/CNT was successfully ap...

Description
Summary:A hierarchical architecture designated as Fe 5 C 2 @Ns-rGO/CNT, consisting of carbon nanotubes, steam activated N-doped reduced graphene oxides, and activated iron carbide nanoparticles, was prepared via microwave irradiation and subsequent CO activation. The Fe 5 C 2 @Ns-rGO/CNT was successfully applied to a rapid CO hydrogenation reaction showing extremely high activity of 4.4 × 10 −3 mol CO g Fe −1 s −1 at a fast gas velocity of 210 NL g cat −1 h −1 .
