Abstract

BaY zeolites are very promising catalysts for catalytic NO _x reduction. The structural and catalytic properties of BaY, Faujasite zeolites were studied using synchrotron based time-resolved XRD and XANES. Dehydration and NO ₂ dosing were employed as probe methods. The location of the Ba cations changed because of interactions with the gas molecules. In the model generated from Rietveld refinement, a N ₄O ₆ cluster was found in the supercage, and a different N containing species was observed on a Ba site. The changes to this structure during thermal heating were also followed. Implications for SCR and zeolite sensors are also presented. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
