Description	Série katalyzátorů připravených termickým rozkladem Co-Mn-Al hydrotalcitů s různými poměry Mn/Al byla testována pro rozklad N2O s důrazem na vliv molárního poměru Mn/Al na dosaženou aktivitu. Katalytická aktivita klesala v pořadí Co4MnAl > Co4Mn1.5Al0.5 Co4Mn0.5Al1.5 Co4Al2 Co4Mn2. Nejaktivnější katalyzátor obsahoval jak optimální poměr Mn/Al tak optimální množství složek redukovatelných v teplotním intervalu testované reakce. Získané výsledky jsou v souladu s hypotetickým mechanismem rozkladu oxidu dusného. (cs) A series of catalysts was prepared by thermal treatment (500 °C) of Co-Mn-Al layered double hydroxides with various Mn/Al ratios with aim to study the effect of Al content on the activity of Co-Mn-Al catalysts in N2O decomposition. Catalytic activity decreased in order Co4MnAl > Co4Mn1.5Al0.5 Co4Mn0.5Al1.5 Co4Al2 Co4Mn2. The most active Co4MnAl catalyst contains both optimal Mn/Al ratio and amount of components reducible in the range in which the catalytic reaction proceeds, as is obvious from TPR measurements. The obtained results are in accordance with the hypothetical mechanism of N2O decomposition.
