High-stability high-permeability compact ceramic oxygen-permeation membrane and preparation method thereof
A disclosed high-stability high-permeability compact ceramic oxygen-permeation membrane is composed of, in percentage by volume, 75-92% of an oxygen ion conductor phase and 8-25% of an ion-electron conductor phase; the oxygen ion conductor phase is a doped CeO2 porous matrix, and the ion-electron mixed conductor phase is a perovskite structure oxygen ion-electron mixed conductor and is disposed in a connected pore channel of the matrix. Additionally, the invention also discloses a preparation method for the above high-stability high-permeability compact ceramic oxygen-permeation membrane. The technical scheme effectively solves the problem that a ceramic oxygen-permeation membrane cannot simultaneously possess the long-term stability and the high oxygen permeation flux in the prior art. The oxygen permeation flux is improved, and also the high-stability high-permeability compact ceramic oxygen-permeation membrane has good long-term working stability.
