- Abstract
- Exposure of NO2-saturated BaO/gamma-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
