Abstract

NOx uptake and S resistance performance was studied over Pt–Ba and Pt–K lean NOx trap (LNT) catalysts, supported on “standard” Al2O3 and a nanofibrous Al2O3. The activity study was accompanied by TEM, XRD and H2 chemisorption characterization. The nanofibrous Al2O3-supported catalysts resulted in better performance. This included improved storage capacity, reduction efficiency during the regeneration phase, thermal stability and S-tolerance.
