摘要	Conventional mesoporous catalysts are generally obtained through the dispersion of active phases on porous supports to enhance catalytic performance. However, metal-support interactions can suppress the activation of iron oxides, and this can lead to lower catalytic activity. Moreover, the effects of supports on catalytic performance are complicated for Fischer-Tropsch (FT) synthesis. Herein, we developed novel mesoporous Fe-based spindles and the pores are self-assembled via active phases. This unique structure effectively avoids metal-support interactions during activation and FT synthesis, thus improving the FT activity. More importantly, the selectivity for C5+ hydrocarbons is found to be correlated with the pore size. It is identified that Fe/2CTAB, which has the largest pore volume among the three mesoporous spindles (Fe, Fe/CTAB, and Fe/2CTAB), affords the optimum C5+ selectivity, up to 65 wt%. This value is much higher than those for traditional co-precipitation catalysts and supported Fe-based catalysts. Moreover, FT synthesis over Fe/2CTAB leads to the lowest CH4 selectivity.
