Abstract

Perovskite oxides are promising materials as oxygen carriers in chemical looping applications. We analyze in situ X-ray diffraction data on the perovskite phases La_1−xSr_xCoO_3−δ for x = 0, 0.25, 0.5, and 0.75 under chemical looping conditions. We report and discuss their structural evolution, cycling stability, and suitability as oxygen storage materials.
