Abstract

Exposure of NO₂-saturated BaO/γ-Al₂O ₃ NO_x 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 NO_x storage/reduction properties of these materials.
