Schematic view of VO (a) in pure CeO2, (b) on the nearest neighbouring oxygen site surrounding Y in Y-doped CeO2, (c) on the next nearest neighbouring oxygen site surrounding Y in Y-doped CeO2 and (d) on an oxygen site in between two Y dopant atoms. The large yellow spheres, large green spheres, small red spheres and small black spheres represent the Ce, Y and O atoms and VO, respectively.
