Abstract
- La<subscript>0.3</subscript>(Ba<subscript>0.5</subscript>Sr<subscript>0.5</subscript>)<subscript>0.7</subscript>Co<subscript>0.8</subscript>Fe<subscript>0.2</subscript>O<subscript>3− δ</subscript> is a promising bifunctional perovskite catalyst for the oxygen reduction reaction and the oxygen evolution reaction. This catalyst has circa 10 nm-scale rhombohedral LaCoO<subscript>3</subscript> cobaltite particles distributed on the surface. The dynamic microstructure phenomena are attributed to the charge imbalance from the replacement of A-site cations with La<superscript>3+</superscript> and local stress on Co-site sub-lattice with the cubic perovskite structure.
