Highly stable Fe-based catalyst from partially leached Al-Fe-Si alloy for hydrogenation CO 2 to light olefins

Key Points

• The aim is to develop a stable Fe-based catalyst through partial leaching of an Al-Fe-Si alloy for CO2 hydrogenation to light olefins.
• Conducted partial alkali-leaching of Al-Fe-Si alloy
• Synthesized an Fe-based catalyst
• Evaluated catalytic activity and stability for CO2 hydrogenation
• Achieved 55.2% selectivity for light olefins
• Demonstrated high catalytic activity
• Showed enhanced stability compared to traditional catalysts
