Catalytic performance and characterization of Co-Fe bcc alloy nanoparticles prepared from hydrotalcite-like precursors in the steam gasification of biomass-derived tar

- Optimized Co-Fe/Mg/Al showed high activity and resistance to coke.
- The Co-Fe/Mg/Al exhibited higher catalytic performance than Co-Fe/α-Al2O3.
- The Co-Fe/Mg/Al consisted of Co-Fe bcc alloy and MgAl2O4-based solid solution.
