- •
K2CO3 facilitated the conversion of Fe3O4 to Fe3C besides developing micropores.
- •
Fe3O4 functioned as an activation promoting agent while providing the Fe source.
- •
A series of K-related species was formed in the whole process.
- •
A three-step reaction mechanism Fe3O4 → FeO → Fe → Fe3C was provided.
