Preparation and Properties of LDH-related Mixed Oxides Deposited on Al2O3/Al Support
Kovanda, F. ; Jirátová, Květa
Deposition of thin active layer on Al2O3/Al supporting material (anodized aluminum foil) during reaction with aqueous solutions of various metal nitrates under hydrothermal conditions, as well as physical chemical properties and catakytic activity of the realted mixed oxides in total oxidation of ethanol was studied.
Aktivita směsných oxidů přechodných kovů nanesených na nosič Al2O3/Al při úplné oxidaci VOC
Jirátová, Květa ; Kovanda, F. ; Klempa, Jan ; Ludvíková, Jana ; Krúpa, L. ; Gaálová, Jana
The MII-(Mn)-Al and MII-Cu-(Mn)-Al LDH precursors (MII = Ni and/or Co) were deposited on Al2O3/Al support during hydrothermal reaction in aqueous solutions containing divalent metal cations. Only a slight incorporation of Mn into deposited solid was observed. The obtained LDH films consisted of thin platelet crystals oriented nearly perpendicularly to the support; their morphology did not change even after heating at 500 °C, when mixed oxides were formed. The deposited mixed oxides containing Cu showed reduction peaks at the lowest temperatures, and, from that reason, the Cu-containing catalysts, namely the Ni-Cu-(Mn)-Al sample was the most active in the total oxidation of ethanol.
