Název v původním jazyce

Supported Co-Mn-Al mixed oxides as catalysts for N2O decomposition.

Popis výsledku v původním jazyce

The Co-Mn-Al mixed oxide catalysts on different supports (TiO2, SBA-15, Al2O3, SiO2, MMT, steel slag, granular blast furnace slag) were prepared by pore filling impregnation, characterized by AAS, XRD, TPR-H2 and N2 physisorption and tested for N2O catalytic decomposition in kinetic regime in an inert gas and in the presence of O2, H2O and NO. The catalytic properties were compared on the basis of specific activities, related to the amount of cobalt and manganese in each sample. The highest activities were observed over Co-Mn-Al mixed oxide supported on SBA-15 and TiO2 and the lowest on slags; the same trend was maintained in the presence of H2O, O2 and NO. The dependence of the specific activity on the ease of catalyst reducibility was observed, whatmeans that tested supports affected properties of active components.
