Epitaxially Grown Heterostructured SrMn₃O_6−x‐SrMnO₃ with High‐Valence Mn^3+/4+ for Improved Oxygen Reduction Catalysis

Angewandte Chemie International Edition, Journal Year: 2021, Volume and Issue: 60(40), P. 22043 - 22050

Abstract Heterostructured catalysts show outstanding performance in electrochemical reactions owing to their beneficial interfacial properties. However, the rational design of heterostructured with desired properties and charge‐transfer characteristics is challenging. Herein, we developed a SrMn 3 O 6− x ‐SrMnO (SMO ‐SMO) heterostructure through epitaxial growth, which demonstrated excellent electrocatalyst for oxygen reduction reaction (ORR). The formation high‐valence Mn 3+/4+ promoting positive shift position d‐band center, thereby optimizing adsorption desorption ORR intermediates on heterojunction surface resulting improved catalytic activity. When SMO ‐SMO was applied as an air‐electrode catalyst rechargeable zinc‐air battery, high output voltage power density achieved, comparable battery prepared Pt/C‐IrO 2 catalysts, albeit much better cycling stability.
