Title: Water-induced Morphology Changes in BaO/g-Al2O3 Nox Storage Materials

Abstract

Exposure of NO{sub 2}-saturated BaO/{gamma}-Al{sub 2}O{sub 3} NO{sub x} storage materials to H{sub 2}O vapor results in the conversion of surface nitrates to Ba(NO{sub 3}){sub 2} crystallites, causing dramatic morphological changes in the Ba-containing phase, demonstrating a role for water in affecting the NO{sub x} storage/reduction properties of these materials.
