Abstract：The perovskite-type La0.8Sr0.2CoO3 supported on the mullite fiber porous ceramics was prepared by means of the impregnating method, and was then characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD); thus we can come to the conclusion that the perovskite-type composite oxidant can disperse on the surface of mullite fiber ceramics. The catalytic activity of the La0.8Sr0.2CoO3 for NO and CO was evaluated. The effect of the doped 0.1 wt-% PdCl2 on the catalytic activity of the perovskite-type La0.8Sr0.2CoO3 was also discussed. The results show that the conversion rates of NO and CO respectively reaches 74.5% and 99% at 601°C without doped Pd, and both reach 100% at 350°C with a little doped Pd.
