    Structured mixed oxide catalysts were prepared by the calcination of layred double hy/droxides (LDHs) deposited on Al2O3/Al supports (anodized aluminum foil). The deposition of LDH precursors on the support was carried out under hydrothermal conditions at 140 °C in aqueous solutions of Ni, Co, Cu, and Mn nitrates. An increased pH of the solutions enhanced the formation of LDH phases. After heating at 500 °C, spinel-like and/or NiO-like oxides were detected in the supported mixed oxides. Among the supported catalysts, the Ni-Cu-(Mn)-Al mixed oxide was the most active in the total oxidation of ethanol. Increasing the pH of solutions used during the hydrothermal deposition resulted in improved catalytic activity and selectivity of the supported mixed oxides.
