The graphitic carbon nitride (g-C3N4) coated alumina (CN-Al) is investigated as a support material for cobalt-based Fischer-Tropsch synthesis (FTS) catalyst. The g-C3N4 weakens the interaction between cobalt and alumina, hinders the formation of irreducible cobalt oxide species, and improves the dispersion of metallic cobalt species on the CN-Al support. The coated g-C3N4 is decomposed during the pre-annealing process under inert condition to evolves reductive gases(Carbon monooxide) to generate the metallic cobalt. Hence, the catalyst can be activated without typical hydrogen pretreatment. Moreover, because of the improved dispersion and reducibility of the cobalt species on CN-Al support, the catalytic FTS activity is higher compared to the conventional Co/Al2O3 catalyst. |
