摘要

Mayenite (Ca12Al14O33), a nanoporous oxide with a unique cage structure, has emerged as a promising oxide-ion conductor for solid oxide fuel cells and oxygen sensors. This review systematically summarizes recent advances in synthesis methods, doping strategies, and mechanistic understanding of oxygen-ion transport in mayenite. Challenges and future directions for optimizing its ionic conductivity are also discussed.
