Abstract

Crystal structure and oxygen storage properties of A-site ordered BaY _{1 - x}Pr_xMn₂O_{5 + δ} (x = 0, 0.25, 0.5, 0.75 and 1) perovskite-type oxides are reported, showing almost complete and reversible change (Δδ > 0.94 mol mol^{- 1}) occurring between fully reduced BaY_{1 - x}Pr_xMn ₂O₅ and oxidized BaY_{1 - x}Pr_xMn ₂O₆ during reduction in 5 vol.% H₂ in Ar atmosphere and oxidation in air at 500 °C. All reduced compounds, as well as oxidized ones for x.
