Abstract

The effect of water and reductants (CO and H2) on the decomposition of NO x stored on BaO/Al2O3 at 300 °C has been investigated. Water eliminates the initial rapid total uptake of NO2 but has little effect on the subsequent formation of nitrates that is accompanied by evolution of NO. Water hinders liberation of NO2 and NO during temperature-programmed decomposition of stored NO x . Both CO and H2 lower the temperatures required for decomposition through reduction of NO2 to NO and N2 thus restricting NO2 readsorption. The rate of reduction is lower with H2 than with CO.
