摘要：

The complex oxide Ba-Fe-O catalysts were prepared by sol-gel method. The XRD, DTA, NO-TPD, XPS and NSC measurements were used to characterize the structures, NO, storage property and sulfur resistance ability. It is concluded that when coadsorption of NO and O-2 at 400 degreesC, the sample calcined at 750 degreesC possesses high NOx storage capacity and sulfur resistance. The perovskite type BaFeO3 and BaFeO3-x, phases are the active centers in the catalyst for NOx storage. (C) 2003 Published by Elsevier B.V.
