摘要：

The influence of the alumina layer nature which acts as the support on the preparation of structured catalysts and on the catalytic performance in VOC combustion was studied. Anodized aluminum and a ferritic alloy covered with colloidal alumina (Nyacol) and theta-delta-Al2O3 were the materials used to prepare the monolith catalysts. The impregnation was performed in one and two stages using two different concentrations of manganese acetate solutions. The catalytic properties of these catalysts were evaluated in ethanol, ethyl acetate, and toluene combustion. The most active catalysts in the combustion of the three molecules were those prepared using a theta-delta-Al2O3 as a Support. The low activity of aluminum monoliths anodized with H2SO4 is due to the presence Of SO42- ions which act as catalyst poison. The anodization with H2C2O4 is a preferable method to prepare MnOx monolithic catalysts.
