WebOct 1, 2024 · The lattice O ions previously coordinated with at least two TM cations become uncoordinated due to the aggregation of vacancies, and thus form O 2 molecules in the trap. Trapped O 2 molecules could be released upon cycling and leave abundant O-vacancies in the bulk, triggering further TM migration and subsequent structural collapse. WebPerovskite oxides are intriguing electrocatalysts for the oxygen evolution reaction, but both surface (e.g., composition) and bulk (e.g., lattice oxygen) properties should be optimized to maximize their participation in offering favorable activity and durability.
