Spinel-like mixed oxides obtained by the calcination of the coprecipitated LDH precursors were characterized by means of chemical analysis, XRD, XPS, BET surface area measurements, TPR, TPD- CO2 and NH3, water adsorption measurements and tested for N2O decomposition to determine the effect of K addition on the catalytic activity in the presence of O2, NOx and H2O. Optimal K content of ca. 0.9 wt% was found to be necessary to achieve a high catalytic activity in the presence of O2 and H2O, while the non-modified Co-Mn-Al mixed oxide was the most active one in the presence of oxygen and NOx."@en .
