TPR Study of Mixed Oxide Catalysts Derived from Mn-Containing Layered Double Hydroxides
 Kociánová, Jana ; Kovanda, F. ; Jirátová, Květa
Posible source of errors appearing during measurements of temperature-programmed reduction was analyzed. TPR measurements enabled us to confirm appearance of various solid phase in the calcined Ni-(Mg)-Mn hydrotalcites in dependence of temperature of calcination.

The Influence of a Metal Particle Size to Adsorptivity and Reactivity in Hydrogenation of Unsaturated Alcohols on Platinum Catalysts
 Francová, D. ; Jirátová, Květa ; Kačer, P. ; Červený, L.
The work is concerned with structure effects exerted by molecules of unsaturated alcohols in heterogeneously catalysed hydrogenation on platinum catalysts. The metod of a competetive hydrogenation was suggested as a suitable kinetic tool for a disscusion on surface complex stability and of a rate of surface in terms of structures of reacting molecules.

Preparation of Eggshell MoO3/Al2O3 Catalyst by the Reaction of Al2O3 with Slurry MoO3/H2O: Effect of MoO3 Dispersion on Rate of Impregnation
 Kaluža, Luděk ; Vít, Zdeněk ; Zdražil, Miroslav
In the present work, we have found that the rate of impregnation was substantially increased by using MoO3 millled in planetary mill.

Calcined Cu(Ni)MgMn Hydrotalcite-like Compounds: Surface Properties, Reducibility and VOC Combustion Activity
 Čuba, Pavel ; Kovanda, F. ; Jirátová, Květa
We have explored metal oxide catalysts prepared from Mn-containing hydrotalcites (HT) and we investigated influence of sulphates amount, porous properties, reducibility and composition of the catalysts (presence of Mg, Cu and/or Ni) on the VOC combustion activity.
