Formation of Nano-porous Structure in a Cathode at the Interface between Pt Electrode and YSZ during CO2 Electrolysis at 1,000 °C

High Temperature Materials and Processes, 2018
The electrolysis of CO2 was investigated using a simple Pt/YSZ/Pt cell (yttria-stabilized zirconia (YSZ)). The cell performance increased drastically after applying the overvoltage of 4.0 V for ~5 min.

Epitaxial MOD-YSZ buffer layers on IBAD-YSZ substrates

Superconductor Science and Technology, 2004
There are a number of reports on the epitaxial growth of MOD buffer layers for coated conductors. However, the quality of superconducting films deposited on top of these layers is often poor. We demonstrate that Y Ba2Cu3O7 (YBCO) layers with a high critical current density of 20 MA cm−2 (8 K) can be deposited on MOD-YSZ (ZrO2:10 mol% Y2O3) which has ...
