Titania Supported Co-Mn-Al Catalysts in Total Oxidation of Ethanol
Ludvíková, Jana ; Jirátová, Květa ; Klempa, Jan
In pelletized mixed oxide catalysts prepared by calcination of coprecipitated precursors, a considerable part of the pellets is not utilized in case of very fast catalytic reaction, due to the effect of internal and external diffusion. Therefore, deposition of thin active layer on a supporting material is advantageous. In this contribution, the effect of the support (titania grains and extrudates) on properties and catalytic activity in VOC oxidation of both catalyst geometric forms were examined.

Total Oxidation of Organic Compounds in Air over Oxide Catalysts
Ludvíková, Jana ; Jirátová, Květa ; Kovanda, F. ; Klempa, Jan
The aim of this work was investigation of the influence of various combinations of metals, Cu, Co, Ni, Mn or Al on properties of LDH (layered double hydroxides)-precursors and their calcined forms, examination of formation of these layered double hydroxides on a model support (anodized aluminum foil), and determination of catalytic activity of the calcined precursors in oxidation of ethanol as model compound.
