Abstract

We measured ion and (implicitly) electron hole conductivities and O2 semipermeabilities and their activation energies of commercial slip-cast Y2O3 doped ZrO2 under conditions simulating their practical application. We believe that this material shows promise as an O2 semipermeable membrane for ROC and electro-ROC type water splitters, as well as components of devices for the gas-phase electrolytic separation of metals (Zn in this study) from their oxides. The higher activation energy for hole transport vis-à-vis ion transport and the associated transition from electrically-dominated to pressure-dominated transport of O2 across such membranes makes an almost continuous transition from electrolytic to thermolytic processes possible. This is especially important in solar processes, where, at high temperatures, the difference between electrochemical and thermochemical processes fades away. This transition greatly increases the latitude with which process variables can be adjusted for optimization.
