A material for separating and pumping oxygen is disclosed. The material is a zeolite doped with a chemical element having an electron density of between 30 kJ/mol and 150 kJ/mol. The material is configured for controllable oxygen desorption between 150° C. and 300° C. and pumping the released oxygen into an area having an ambient pressure of less than 100 pascals.

Material to separate and pump oxygen

The present disclosure is directed to methods using durable functional materials for processes that include an oxidation step. The durable functional materials are redox active oxygen carrier materials that include a zirconia or yttria-stabilized-zirconia (YSZ) matrix containing a redox-active metal ion(s), such as, but not limited to Fe, Mn, Cu, Co and Cr. In an embodiment, these materials are used in chemical looping processes.
