Název v původním jazyce

Supported mixed oxide catalysts for the total oxidation of volatile organic compounds.

Popis výsledku v původním jazyce

Supported mixed oxide catalysts of various cation composition were obtained by heating (500 °C) of layered double hydroxide (LDH) precursors deposited on Al2O3/Al support (anodized aluminum foil) or grained alumina calcined at various temperatures duringhydrothermal reaction in aqueous solutions of Co, Cu, Ni, and Mn nitrates. The MII-(Mn)-Al LDHs (MII = Co, Ni-Co, Ni-Cu, and Co-Cu) with only low Mn content were obtained. NiO-like and spinel-like mixed oxides but no distinct Cu-containing phases were detected in the supported catalysts. A low-temperature peak ascribed to reduction of an amorphous copper oxide was detected in TPR patterns of the supported mixed oxides containing Cu. TPR results indicated reduction of Ni- and Co-containing species at temperatures higher than 400 °C; it can be explained by formation of spinel-like phases and high structural ordering of the calcination products. Heating of grained alumina support at high temperatures (}550 °C) resulted in substantial decr
