Carbon defects promoting syngas into liquid fuels over Fe₃C@C catalysts

Carbon wrapped iron catalysts have been intensively studied in recent years to achieve efficient syngas conversion into high-value-added chemicals. A Fe3C@C catalyst with defect-rich graphite shell exhibits C5+ selectivity of 70.1% and CH4 selectivity of 9.0% at CO conversion of 55.2%, which can be attributed to the enhanced reactant adsorption and anti-oxidation of Fe3C during FTS.
