| Description
| - Příspěvek se zabývá katalytickým rozkladem N2O na katalyzátorech připravených kalcinací Co/Mg-Mn/Al hydrotalcitů. Katalyzátory (směsné oxidy) byly charakterizovány pomocí RTG, XPS, IR a Ramanovy spektroskopie, TPD a TPR a byl stanoven měrný povrch (BET). Aktivita katalyzátorů pro rozklad N2O byla testována v inertním plynu a v přítomnosti kyslíku a vodní páry. Jako nejaktivnější katalyzátor byl vyhodnocen katalyzátor připravený z Co hydrotalcitu obsahující trojmocný Al a Mn. Redoxní vlastnosti katalyzátoru hrají významnou roli v dané reakci a bylo zjištěno, že je nutný optimální stupeň redukce pro dosažení vysoké katalytické aktivity. Na základě získaných výsledků byl navržen redoxní model rozkladu N2O. Při nízkých koncentracích N2O a O2, typických pro odpadní plyny, lze rozklad N2O popsat kinetikou prvního řádu. (cs)
- Co/Mg-Mn/Al hydrotalcite-like compounds were prepared by coprecipitation method. The mixed oxides obtained by calcination at 500 °C were characterized using various techniques (XRD, XPS, IR and Raman spectroscopy, BET surface area measurements, TPD and TPR). The activities of calcined hydrotalcites were tested for N2O decomposition in an inert gas, and in the presence of oxygen and water vapor as well. Among the catalysts screened, the catalyst prepared from Co hydrotalcite containing Al and Mn as the trivalent cation showed the highest activity. Redox properties of the catalysts play an important role in the reaction and optimum extent of reduction is necessary for achievement of the highest catalytic activity. Based on the obtained results a redox model of N2O decomposition was proposed. At N2O and O2 concentrations typical for waste gases, N2O decomposition is well described by the 1st rate law.
