Enhanced oxygen storage capacity of cation-ordered cerium–zirconium oxide induced by titanium substitution

Abstract

Herein, we report on the synthesis of Ce0.5Zr0.5−xTixO2 oxygen storage materials prepared via a solution combustion method. Ce0.5Zr0.4Ti0.1O2 showed an outstanding oxygen storage capacity (1310 μmol-O per g) at 200 °C compared to conventional κ-Ce2Zr2O8 (650 μmol-O per g) due to its cation ordering and the formation of weakly bound oxygen atoms induced by Ti substitution.
