Abstract:Ce 0.6Zr 0.4O 2 solid solution was prepared by coprecipitation technique and characterized by XRD and specific surface area measurements. Ce 0.6Zr 0.4O 2 was used to prepare palladium-only three-way catalyst(TWC) and its influence on the performance of TWC was investigated. The results show Ce 0.6Zr 0.4O 2 has a cubic structure similar to CeO 2, but its specific surface area decreased slowly as the calcination temperature increased. Being aged at high temperature Ce 0.6Zr 0.4O 2 still showed higher conversion of HC, CO and NO and lower lightening temperature in comparison with CeO 2 TWC.
Keywords:ceria-zirconia solid solution  three-way catalyst  performance
