- Abstract
NO uptake and S resistance performance was studied over Pt-Ba and Pt-K lean NO trap (LNT) catalysts, supported on 'standard' AlO and a nanofibrous AlO. The activity study was accompanied by TEM, XRD and H chemisorption characterization. The nanofibrous AlO-supported catalysts resulted in better performance. This included improved storage capacity, reduction efficiency during the regeneration phase, thermal stability and S-tolerance.
