%X A series of Ce-Zr-Mn compound oxides oxygen storage materials were synthesized by a co-precipitation method and characterized by X-ray diffraction (XRD),BET,oxygen adsorption and temperature programmed reduction (TPR).The modification of the textural and structural properties,oxygen storage capacity,redox behavior,and phase changes were investigated.The results show that incorporating a small amount of manganese into Ce-Zr solid solution can re- markably improve the oxygen storage capacity and decrease the temperature of the reduction of the oxygen storage materials.Moreover,only a stable cubic phase CeO_2-ZrO_2 solid solution is formed.The Ce-Zr-Mn Compound oxide indicates the highest oxygen storage capacity (OSC) and excellent property of resistance to aging when manganese content (mole fraction) is 0.025,its surface area can reach 57.8m~2/g after aging 5h at 1273K.
