Abstract

In this work, we present results showing modification of the oxygen storage-related properties of perovskite-type oxides based on BaYMn<inf>2</inf>O<inf>5+</inf>δ, having A-site layer-type cation order. Y<sup>3+</sup> is the lightest among suitable cations, which allows to obtain such the structural order, and at the same time, it provides the highest theoretical oxygen storage capacity. However, substitution of Y<sup>3+</sup> by Sm<sup>3+</sup>cations may be beneficial, and BaY<inf>0.5</inf>Sm<inf>0.5</inf>Mn<inf>2</inf><inf>O</inf>5+δ material shows enhanced reduction kinetics. Furthermore, partial substitution of Ba<sup>2+ by Sr</sup>2+ increases reversible oxygen storage capacity, but at the same time slows down the reduction speed. In addition, for higher concentration of strontium, it is not possible to obtain single phase materials.
