Abstract X-ray photoelectron spectroscopy measurements indicate that the Ce3+ fraction in Al2O3-supported CeO2 can be decreased by the incorporation of La3+. If La3+ is incorporated into the Al2O3 before CeO2 is added, a higher CeO2 dispersion and a greater range of reversible reducibility of the CeO2 may also be obtained. These changes offer potential for improvement in the oxygen storage capacity provided by CeO2 in three-way catalysts.
