Remarkable Oxygen Intake/Release Capability of BaYMn2O5+δ: Applications to Oxygen Storage Technologies
Source abstract
Abstract
Here, we report the remarkable oxygen intake/release capability of a double perovskite BaYMn 2 O 5+δ . 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 BaYMn 2 O 5+δ 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 flameless combustions of hydrocarbons, presumably owing to its oxygen-storage ability.
