Tuning the Activation Barrier for Oxygen Exchange on Mixed Conducting Oxide with Fine Control of Transition Metal Impurities

Abstract The energy barrier for oxygen exchange at the surface of mixed conducting oxides is a multifactor term that remains difficult to predict with existing models. Here, we describe an experimental approach to fine-tune this barrier on Pr0.1Ce0.9O2-δ used as a model mixed con...
