Here, we report the remarkable oxygen intake/release capability of a double perovskite BaYMn2O5+delta. This oxide rapidly stores/releases a large amount of oxygen (> 3.7 wt %) at moderate temperatures in a perfectly reversible manner. The oxygen intake/release behaviors of BaYMn2O5+delta are clearly beyond those of any conventional oxides in terms of the magnitude and sharpness of the processes. It also appeared that this oxide exhibits a significant catalytic activity for nameless combustions of hydrocarbons, presumably owing, to its oxygen-storage ability.
