| 英文摘要 | manganese served as promoter for the fe-based catalysts has been considered to have great potential in fischer-tropsch (ft) synthesis. however, many previous researchers mainly focus on the enhancement of lower olefins, primarily because the previous reported fe-mn spinel oxide hindered its wide applications. in this article, fe2o3@mno2 spindles were fabricated by coverage of hematite with mno2 via a hydrothermal reaction and applied in ft synthesis reaction. different from the conventional fe-mn catalysts, the synthesized core-shell catalysts exhibited enhanced catalytic performance, especially in c5+ hydrocarbons selectivity. it demonstrated that mn promoter could accelerate the dissociation of co and thus enhanced the concentration of active intermediates for chain growth. compared with the pure fe2o3 (mn-free) catalyst, the selectivity toward c5+ hydrocarbons over fe2o3@mno2 (mn-9) catalyst was increased from 44.6 to 66.6 wt%. meanwhile, the undesired ch4 was decreased from 16.8 to 8.9 wt%.
