Abstract

Ce_0.6Tb_0.1Zr_0.3O₂ solid solution was prepared by the coprecipitation technique and characterized by XRD and specific surface area measurements. Ce_0.6Tb_0.1Zr_0.3O₂ was used for the preparation of palladium-only three-way catalyst (TWC) and the performance of the TWC was evaluated. The results show that Ce_0.6Tb_0.1Zr_0.3O₂ has similar cubic structure with Ce_0.6Zr_0.4O₂ whose phase is homogeneous and stable and it has higher specific surface area. The TWC containing Ce_0.6Tb_0.1Zr_0.3O₂ has higher catalytic activity and a wider operation window of air/fuel ratio and lower light-off temperatures of 177°C, 173°C and 176°C for HC,CO and NO, respectively. Ce_0.6Tb_0.1Zr_0.3O₂ is suitable for the oxygen storage material of a new generation of TWC.
