Isothermal CO₂ conversion to CO was achieved at 550°C using the Reverse Water Gas Shift Chemical Looping process. Fe-doped lanthanum strotium cobaltites (La_0.75Sr_0.25Co_1-YFe_YO₃) were synthesized and evaluated by temperature-programmed reduction, oxidation, and x-ray diffraction. Results demonstrated La_0.75Sr_0.25FeO_3-_δ as the most active and stable sample for the reaction.
