A study of the NOx storage catalyst of Ba–Fe–O complex oxide
Catalysis Communications 5 (2004) 25–28，-0001，（）：
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, NOx storage property and sulfur resistance ability. It is concluded that when coadsorption of NO and O2 at 400 C, the sample calcined at 750℃ 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.
