Abstract

The lean NO trap is generally considered as one of the promising solutions for the exhaust control of gasoline lean burn and diesel engine to meet future requirements on emission levels. The results of multi-spectroscopy study were presented to understand the various roles of water on BaO/Al₂O₃ NO storage materials and catalytic activity. The morphological changes of fresh or pre-adsorbed NO₂ BaO/Al₂O₃ materials upon the water treatment were observed. The effect of water in the NO uptake activity especially for the thermally aged samples was studied. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
