Water-induced morphology changes in BaO/γ-Al<inf>2</inf>O<inf>3</inf> NO<inf>x</inf> storage materials

Abstract:

Exposure of NO2-saturated BaO/γ-Al2O 3 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. © The Royal Society of Chemistry.
