The properties of the Mn-Ce/Beta zeolite catalyst in the selective catalytic reduction (SCR) of NOx have been investigated. The introduction of Ce leads to a marked increase in the NO (x) conversion at 100-250 degrees C. The data of this study are consistent with the bifunctional pathway of SCR suggested for Mn/Beta, which consists of two stages-NO oxidation to NO2 over the oxide component and fast SCR over the zeolite. The increased activity of Mn-Ce/Beta at the NO-to-NO2 oxidation stage is due to the formation of MnCeO (x) mixed oxides enhancing the mobility of lattice oxygen. The determining role is played by the activity of the zeolite component in the fast SCR reaction.
