Abstract
- Perovskite oxides are promising catalysts for water oxidation. Herein, we constructed a Sr3CoFeWO9 triple perovskite with Co, Fe, and W atoms sharing octahedral positions. Thermally activated growth of an amorphous FeCoW oxyhydroxide layer on this perovskite pre-catalyst greatly enhanced the oxygen evolution reaction (OER) activities, reducing overpotential at 10 mA cm−2geo by 115 mV. This highlights the benefits of compositional design and structural reconstruction for efficient electrocatalytic materials. [ABSTRACT FROM AUTHOR]
