Oxygen storage capacity and structural properties of Ni-doped LaMnO3 perovskites

Dynamic OSC of (a) fresh and (b) aged LaMn1−xNixO3 perovskites (0.1 Hz). Aged condition: 1050 °C, 5 h, 7% steam in air. The LaMn1−xNixO3 perovskites exhibit considerable dynamic OSC in comparison to CeO2-ZrO2 (CZ), even after 1050 °C hydrothermal ageing for 5 h.
