TL;DR: In this article, the reduction/oxidation behavior of high surface area CeO2 and Ce0.5Zr 0.5O2 mixed oxide is compared, and it is shown that the introduction of ZrO2 into the Ce2 framework with formation of a solid solution strongly modifies the reduction behaviour in comparison to that seen with CeO 2 alone, and that the expansion/contraction of the lattice parameter upon, respectively, reduction andoxidation, detected by X-ray diffraction, is responsible for the textural modification.
