Modifikace NiMgMn směsných oxidů vzácnými kovy a jejich fyzikální a katalitické vlastnosti při totální oxidaci VOC
Mikulová, Zuzana ; Balabánová, Jana ; Kovanda, F. ; Jirátová, Květa
The aim of our work is to improve properties of the calcined NiMgMn catalyst by introducing of small amount (0.1%) of noble metals (Pt, Pd, Ag) from different precursors and to reveal their effect on physical-chemical properties and the activity in total oxidation of toluene and ethanol. Four methods were used for NiMgMn catalyst modification with Pt, Pd or Ag (impregnation, impregnation with a reverse microemulsion, ion exchange or noble metal was incorporated into the precursor during coprecipitation).
Smíšené oxidy připravené tepelným rozkladem vrstevnatých hydroxidů obsahujících Co a Mn
Kovanda, F. ; Dobešová, J. ; Rojka, T. ; Grygar, Tomáš
Many catalysts based on mixed oxides can be obtained by a controlled decomposition of layered double hydroxides (LDHs) and therefore it is of interest to understand in detail the thermal behaviour of these materials.
