A series of MnO_x-CeO₂-Y₂O₃ catalysts with different Y loadings (0, 1, 3, 6, and 10 wt%) were prepared by a co-precipitation method and investigated for NO_x-assisted soot oxidation. The thermal stabilities of these catalysts were evaluated by treating them at 800 ℃ for 12 h under dry air flow. The catalysts were characterized by X-ray diffraction, N₂ adsorption-desorption, Raman spectroscopy, H₂ temperature-programmed reduction, oxygen storage capacity, NO temperature- programmed oxidation, X-ray photoelectron spectroscopy, and soot temperature-programmed oxidation. The addition of Y led to decreased BET surface areas and poor low-temperature reduction abilities and oxygen storage capacities, which affected NO and soot oxidation activities. However, after aging, the doping of Y had effectively enhanced the stability of the catalytic activities for NO and soot oxidations, where the addition of 6%-10% Y achieved the optimum result because the maximal soot oxidation rate temperature was increased by only 34-35 ℃. Additionally, the catalytic activity and deactivation of MnO_x-CeO₂-containing catalysts were closely related to the presence of Mn⁴⁺ and oxygen species on the surface.
