Preparation of high oxygen storage capacity and thermally stable ceria–zirconia solid solution

Abstract

Ce_0.5Zr_0.5O₂ prepared by the complexing–coprecipitation method (CZ-2) exhibits higher oxygen storage capacity (OSC) and thermal stability than that prepared by coprecipitation (CZ-1) or the complexing–coprecipitation-solution (CZ-3) method. After being aged at 1100 °C for 6 h, CZ-2a exhibited the highest OSC and catalytic activity.
