Alkali metals promoted Co-Mn-Al mixed oxide for N2O catalytic decomposition
Original language description
The series of alkali metals promoted catalysts was prepared by impregnation of thermally treated Co-Mn-Al layered double hydroxides (Co/Mn/Al = 4/1/1) with aqueous nitrate solutions of alkali metals using a pore-filling method. In this way prepared samples were characterized by AAS, AES, SEM, XRD, TPR and TPD. The elemental mapping of alkali metals indicated homogeneous promoter distribution on the catalysts' surface. Substantial differences between surface (XPS) and bulk chemical composition (AAS, AES)were observed. Presence of alkali metals promoters in the prepared catalysts influenced both redox (TPR-H2) and acid-base surface properties (TPD-CO2, TPD-NH3). The effect of alkali promoters on the rate of N2O decomposition was investigated in an inertgas. The Li-promoted catalyst was less active for N2O decomposition than the non-modified one, while the same catalytic activity on Na-containing catalyst was observed. On the other hand, rubidium and cesium caused the increase in N2O co
