A series of Ce 0.5Zr 0.5O 2 oxygen storage material samples were prepared by co-precipitation using ammonium carbonate as precipitant. The effect of the concentration of the salt solution on the performance of the target materials and its supported Pd-only catalyst was investigated. The samples were characterized by N 2 adsorption, X-ray diffraction, oxygen storage capacity, and temperature-programmed reduction. The results showed that the prepared material exhibited high thermal stability and perfect redox properties. When the concentration of the salt solution was 0.3 mol/L, the obtained material presented the best textural properties with a surface area of 53.0 m 2/g and pore volume of 0.17 cm 3/g after calcination at 1000°C for 5 h. The corresponding catalyst exhibited higher catalytic activity with relative low light-off and full conversion temperature, showing potential application in automotive catalysts.
