For an application to Fischer-Tropsch synthesis (FTS) reaction, which is an alternative chemical process to convert syngas to synthetic fuels, a novel iron carbide catalyst derived from mesoporous graphitic-C3N4 (Fe/mpg-C3N4) was synthesized by an incipient wetness impregnation method. During the synthesis of Fe/mpg-C3N4, the mpg-C3N4 can supply carbon sources to easily form iron carbide species, which was found to be highly stable and active for FTS reaction. The decomposition of the mpg-C3N4 can enhance a carbo-thermal reduction of iron oxides to iron carbides, which are known to be active species for FTS reaction. The co-presence of iron metal and carbide phases formed during carbothermal reduction step seem to significantly enhance a catalytic activity with an enhanced C5+ hydrocarbon selectivity due to the selective formation of most active χ-Fe5C2 phases. |
