Abstract
Perovskite oxides have been under intense investigation as promising candidates for devices in the field of energy conversion and storage. Unfortunately, these perovskites are probably subjected to a frequent performance loss caused by phase transition. A phase-stabilization approach via interdiffusional tailoring is identified in perovskite-based composites. As an example, a phase-stabilized perovskite-fluorite composite material with both components possessing cubic symmetry was obtained by an appropriate one-pot strategy. These findings render possible to develop a high-performance and extremely stable dual-phase oxygen-transporting membrane for intermediate-temperature air separation as well as syngas production, which also opens up numerous opportunities to overcome the phase-transition-induced performance degradation in other systems.
