Thin layer of active oxides enables their high utilization due to low internal diffusion effects. The stainless steel meshes used as support were treated under hydrothermal conditions in Co and Mn nitrates aqueous solutions containing urea and then heated at 500 °C in air to obtain supported Co-Mn mixed oxides with various Co:Mn molar ratios. The other set of non-supported catalysts was prepared by coprecipitation of Co and Mn nitrates and subsequent heating at 500 °C in air. The XRD, SEM, TPR, and XPS were used for the catalysts characterization and their activity was examined in deep oxidation of ethanol.
