Oxygen ionic conductivity through zirconia (ZrO2) is essential to the performance of solid oxide fuel cells, thermal barrier coatings, and zirconium alloys for nuclear fuel cladding. Since sulfur (S) atoms can replace oxygen atoms at ZrO2 surface or even induce formation of homogeneous zirconium oxy...
