Modulating Oxygen Transfer via A‐Site Doping in LaFeO3 for Coke‐Resistant Chemical Looping Steam Methane Reforming

ChemSusChem, Volume 18, Issue 24, December 13, 2025.
Promoting oxygen mobility within the oxygen carrier is essential for suppressing coke deposition during chemical looping steam methane reforming. A‐site doped LaFeO3 with alkaline earth metals facilitates bulk‐to‐surface oxygen transport, thereby maximizing syngas and hydrogen productivity while inhibiting carbon accumulation.
