Defect‐Engineered IrO <sub>x</sub> @Perovskite Heterostructures via Thermal Reconstruction for Acid‐Stable Oxygen Evolution Catalysis
@LSNF-250 in acidic media are attributed to perovskite-anchored Ir species suppressing dissolution, together with thermal-reconstruction-enriched oxygen defects optimizing LOM. This work establishes a paradigm for defect-engineered heterostructures via thermal reconstruction, advancing perovskite-based OER catalysts beyond conventional stability-activity trade-offs in acidic media.
