AB  - The complete oxidation of n-hexane in air over a stainless steel foil (SS) coated with a thin film of ZrO2 (SS/ZrO2), SS/ZrO2/Pt, SS/ZrO2/La2O3/CuCo and SS/ZrO2/La2O3/CuCo/Pt catalysts has been investigated. The ZrO2 films were deposited on the SS substrate by electrochemical and spray pyrolysis (SP) methods. Among electrochemically prepared samples, Pt containing catalysts exhibited the highest activity. The presence of La, Cu and Co oxides along with Pt did not improve the catalytic activity. The SS/ZrO2/Pt sample prepared by spray pyrolysis showed a much better light-off characteristic than did the electrochemically obtained catalysts. The spray pyrolysis method permits the preparation of thicker ZrO2 films as compared to films prepared by an electrodeposition method. Thus, an increase of the surface area available for deposition of Pt atoms was achieved.

AB  - We have investigated the deposition of ZrO2 and Al2O3 films on a stainless steel (SS) substrate by spray pyrolysis method. The ZrO2 films were deposited from aqueous solution of zirconium dinitrate oxide. For Al2O3 films, a boehmite sol was used. The specific surface areas of samples were determined by the BET-method and sample surfaces were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. The spray pyrolysis method permits the preparation of ZrO2 and Al2O3 thin films on SS with good adhesion. This method enables preparation of oxide layers with relatively high specific surface area, suitable for applications as catalysts supports.

AB  - The influence of low loadings of MnOx on the catalytic activity for n-hexene and CO oxidation over highly dispersed Pt on alumina catalysts has been investigated. The applied deposition-precipitation method allows Mn to be deposited on the Pt containing egg-shell volume. The catalyst samples were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and selective CO chemisorption. Platinum influences the dispersion of deposited MnOx. The dispersion of the MnOx phase is higher on Pt containing samples than on Al2O3. The Pt decoration by Mn is reflected by a low CO uptake and the Pt oxidation state (Pt2+). The addition of Mn lowers the catalytic activity for CO oxidation. This is attributed to a change of the Pt sites such that adsorption of CO is less favorable. The activity of the catalysts in the oxidation of n-hexane showed a significant improvement with addition of MnOx. A light-off shift by about 40 degrees C was observed. This improvement is attributed to the formation of Mn-Pt oxide like species that primarily weakens the Pt-O bond.
