title = "Lean NOx trap morphology changes with lean/rich cycling",
abstract = "The fundamentals of NO uptake/release processes have been studied extensively on NO storage/reduction catalysts (also known as lean-NO traps (LNT) and NO adsorber catalysts) based on BaO on alumina support. To understand the processes that take place upon NO adsorption on these BaO/Al2O3 catalysts in different reactant gas mixtures, and in the subsequent regeneration, studies utilizing a series of spectroscopic techniques were carried out. The adsorption of NO was examined on 2, 8, and 20\% BaO/Al2O3 catalysts with or without Pt using a series of in situ spectroscopic techniques. A morphology cycle that the BaO/Al2O3 systems go through during NO uptake and release was proposed. The effects of high temperature processes on the morphologies and performance of these model LNT catalysts were examined. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).",
