中文摘要：

混合导体透氧材料由于在高温下具有氧离子导电特性，在纯氧制备、膜反应器及富氧燃烧等方面显示出广阔的应用前景。单相混合导体材料用作透氧材料时存在稳定性不足、机械性能差等问题，限制了其在生产中的实际应用。在离子导体相中掺入电子导体相形成双相导体膜可以提高透氧材料在高温下和高氧浓度梯度下的工作稳定性和化学稳定性。本文详细论述了双相透氧材料的透氧机理和研究进展，包括氧离子导体／贵金属电子导体和氧离子导体／氧化物电子导体和氧离子导体／混合导体等的复合形式。重点分析了材料的组成、结构以及两相之间的化学相容性和混合比例对材料透氧率和工作稳定性的影响。介绍了双相材料在甲烷部分氧化制合成气（POM）膜反应过程及富氧燃烧中的应用，分析了目前有待解决的问题并提出了今后的研究方向。

英文摘要：

Mixed conducting membranes that exhibit oxygen ion conduction at elevated temperature are of significant interest due to their potential applications for oxygen production, partial oxidation of methane to syngas （POM）, and oxygen-enriched combustion. Well-investigated single-phase conductors show some disadvantages, such as poor long-term stability and low mechanical strength, limiting their practical applications. The dual phase membrane made from ionic and electronic conducting phases could improve the performance of long-term stability and chemical stability at elevated temperature and high oxygen partial pressure gradient. In this paper, the oxygen permeation mechanism and the research progress in dual-phase membranes are reviewed, including ion-conducting phase/noble metal, ion-conducting phase/electron-conducting oxides, and ion-conducting phase/mixed conducting phase. The emphasis is focused on the effect of composition, lattice structure, and the chemical compatibility and mixing ratio of the two phases on the oxygen permeability and operation stability of the dual phase membrane. Their applications in POM and oxygen-enriched combustion are introduced. The present problems concerned with dual phase membrane are concluded and the main future research directions are proposed.
