Cerium-based materials were intensively studied in last years because of their high oxygen storage capacity (OSC) associated to the reversible Ce4+ Ce3+ process and their properties closely related to the defect chemistry that could be adjusted by adequate selection of dopant. Fe3+ cation, due to its effective ionic radius smaller than that of Ce4+, is an interesting doping agent. In this work we present the synthesis and characterization of Ce(1-x)FexO2-δ mixed oxides (0
