Structure-dependent electronic modulation of Pt on perovskite surfaces: bifunctional oxygen catalysts for rechargeable Zn–air batteries

Key Points

Investigate how the structure of perovskite affects the electronic properties of platinum for use in Zn-air batteries.
Analyzed the structural characteristics of perovskite materials.
Examined the electronic modulation of platinum on these surfaces.
Evaluated the performance of modified platinum in Zn-air battery configurations.
Demonstrated improved cycle stability in Zn-air batteries with modified platinum.
Identified a unique oxygen spillover pathway contributing to enhanced performance.

Abstract

The electronic modulation of surface platinum is facilitated by the hexagonal structure of the perovskite. This structural feature enables especially remarkable cycle stability in Zn–air batteries through a distinctive oxygen spillover pathway.
