Název v původním jazyce
NO direct catalytic decomposition over cobalt based mixed oxides modified by potassium.
Popis výsledku v původním jazyce
The main aim of keynote lecture at 15th Pannonia International Symposiu on Catalysis n jastrzebia Gora Poland 4-8.9.2022 was to present tresults on potassium modified Co based mixed oxide catalysts with respect to the direct catalytic NO decomposition - understanding of reaction mechanism, active sites formation and catalyst stability. To achieve this, the K/Co-Mn-Al containing catalysts were prepared via different methods, characterized (AAS, ICP, XRD, XAS, N2 physisorption, TPR H2, TPD NO/O2/NO+O2, TPD CO2, SEM, TEM, XPS, TGA, WF, SR-TAD) and tested for NO catalytic decomposition (dynamic and steady state experiments) in inert and in O2, H2O or CO2 presence. The effect of active phase precursor (hydrotalcite, nitrate, carbonate), K promoter precursor (nitrate, carbonate, oxalate, acetate), the way of K deposition (impregnation, wet cake impregnation, coprecipitation), presence and amount of structural promoter (Mn, Zn, Mg, Pb), additional electronic promoter (Ce) and reaction mechanism were studied. Catalytic tests were focused on activity, stability and deactivation features.
