Activity of Fe-based oxygen carrier for hydrogen generation is tested with TGA. The most probable mechanisms for the redox reactions are determined. The reaction rate constants for the redox processes are calculated. The final forms of iron after the experiments are detected. The oxygen carrier reactivity becomes stable within 7 redox cycles.
