Facile fabrication of porous Fe@C nanohybrids from natural magnetite as excellent Fischer-Tropsch catalysts

Fe-based catalysts play crucial roles in Fischer-Tropsch synthesis (FTS). Herein, we firstly demonstrated a facile sol-gel approach using natural magnetite and citric acid to fabricate porous Fe@C nanohybrids as FTS catalysts. Excellent FTS activity and stability were revealed which attributed to the formation of Fe3C active phase and core-shell structure. This flexible synthesis strategy clearly highlights the promising application of such materials in FTS.
