Water-induced morphology changes in BaO/?-Al2O3 NOx storage materials

Abstract

Exposure of NO2-saturated BaO/?-Al2O3 NOx storage materials to H2O vapour results in the conversion of surface nitrates to Ba(NO3)2 crystallites, causing dramatic morphological changes in the Ba-containing phase, demonstrating a role for water in affecting the NOx storage/reduction properties of these materials.
