Abstract

Abstract : Fe5 C2 @Ns-rGO/CNT was prepared and applied to a rapid CO hydrogenation reaction, showing high activity under high gas velocity. The performance was attributed to high surface area, 3D-interconnected pores, apt for fast mass transport, and N-doped enhancing the catalytic activity. Abstract : A hierarchical architecture designated as Fe5 C2 @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 Fe5 C2 @Ns-rGO/CNT was successfully applied to a rapid CO hydrogenation reaction showing extremely high activity of 4.4 × 10 −3 molCO gFe −1 s −1 at a fast gas velocity of 210 NL gcat −1 h −1 .
