Application of NOX storage/release materials based on alkali-earth oxides sup…

Abstract. Alkali-earth oxides and nitrates supported on alumina were studied as model systems for NOX storage/ release. Their impact on the high-temperature soot oxidation has been investigated. The stability of surface nitrates and temperature of NOX release increase parallel to the basicity of the cation. The presence of soot decreases the temperature of NOX release. The storage capacity …
