Effects of Doping Manganese on the Properties of Ce-Zr Compound Oxides

doi:10.3724/SP.J.1077.2006.01417

Abstract

Abstract: 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 remarkably improve the oxygen storage capacity and decrease the temperature of the reduction of the oxygen storage materials. Moreover, only a stable
cubic phase CeO₂-ZrO₂ 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 57.8m²/g after aging 5h at 1273K.

Key words: Ce-Zr-Mn compound oxides, OSC, reducibility, resistance to aging
