In situ monitoring of the oxygen content of dual phase oxygen transport membranes by thermogravimetry and neutron diffraction
Combined in situ neutron diffraction and thermogravimetry at D1B will beused to track the change of the oxygen content in the dual-phase oxygen transport membrane material Ce0.8Pr0.2O2-x/La0.5Sr0.5Fe0.8Cu0.2O3. The sample shows deviating thermal behavior in comparision to CeREO2-x (RE = La, Nd, Sm, Gd) having together with Gd containig the highest oxygen permeation flux, but they differ totally in there thermal behavior. Neutron diffraction is needed to monitor the individual changes in the oxygen content in fluorite and perovskite phase.
