The Fischer-Tropsch (FT) technology can over all area of petroleum not only energy and fuel but also petrochemical products, because this technology produces real oil and olefin during the process. Iron is well known as good active catalyst material for FT synthesis reaction, especially for their high selectivity to olefin or branched hydrocarbon products. Herein, we prepared the Fe-based catalyst over g-C3N4, which accelerates the activating the metallic iron to iron carbide. The iron species with g-C3N4 is reduced much easier than which on carbon nanotubes, and after in successive FTS reaction condition, reduced metallic iron is easily carburized. In the consequence, iron catalyst over g-C3N4 showed much higher CO conversion than over carbon nanotubes (~80% over g-C3N4 and ~20% over carbon nanotubes at the same condition). The phase transition of iron species is investigated by various analysis tools including XRD, XPS, BET, XAFS, TEM, and TPR, etc. |
