Ahighly active MnOx materials were prepared by an oxidation-reduction reaction between KMnO4 and Mn(NO3)2. The γ-Al2O3 support with large surface area was synthesized by the peptizing method. Subsequently, Pd was loaded on MnOx and γ-Al2O3 by incipient wetness impregnation, respectively. Then, the Pd/MnOx and Pd/γ-Al2O3 were mixed and coated on the cordierite. Finally, the Pd/MnOx+Pd/γ-Al2O3 monolithic catalysts were obtained. The catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Temperature-programmed reduction (H2-TPR) and low temperature N2 adsorption/desorption measurement, respectively. Asynergetic effect took place between Pd and MnOx when O3 was decomposed on the surface of the Pd/MnOx+Pd/γ-Al2O3 catalysts. The effect of calcination temperature on the catalytic performance for the decomposition of ground-level ozone was investigated. It revealed that the activity of catalysts was considerably influenced by the calcination temperature of MnOx. When the MnOx was calcined at 600 ℃, the catalyst had the highest activity, where ozone conversion reached 88% at 12 ℃ and it was completely decomposed at 18 ℃. The results show that catalytic activity mainly depends on the MnOx phase and oxygen species adsorbed on the surface of catalysts. The MnO2 and Mn2O3 with proper proportion can efficiently promote the decomposition of ozone. And oxygen adsorbed on the surface of catalysts is active oxygen species during ozone decomposition.
