Doped and undoped cerium(IV) oxides are ceramics commonly used as catalysts and as solid oxide fuel cell materials. In low oxygen partial pressure, ceria-based materials become non-stoichiometric and can form defect complexes that hinder ionic conductivity. In addition, oxygen non-stoichiometry indu
