A hierarchical structure designated as Fe5C2@Ns-rGO/CNT, consisting of CNT branches on the steam-activated reduced graphene oxide, N-doping and activated Fe5C2 catalysts via microwave irradiation and following CO activation. The hybridzation of CNT with s-rGO has been resarched due to large specific surface area, fast mass transfer and mechanical-chemical stability. The Fe5C2@Ns-rGO/CNT was effectively applied to a rapid CO hydrogenation reaction showing extremely high activity of 4.4 x 103 molCO gFe-1 s-1 at a fast gas velocity of 210 NL gcat-1 h-1.
