Catalysts in the present study were prepared as follows: Stainless steel meshes used as supports were coated with thin Co3O4 film by RF magnetron sputtering and further Co3O4 layer by subsequent electrochemical deposition followed by heating. The meshes with deposited Co3O4were then coated with additional MnO (samples A-C) or Co-Mn mixed oxide (Co:Mn molar ratio of 1:3, samples D-F) thin films of various thickness (approximately 100, 200, and 300 nm) by RF magnetron sputtering and heated at 500 °C in air. The structured Co-Mn oxide catalysts with various Mn content were examined by XRD, SEM, FTIR, XPS, and H2-TPR, tested in the gas-phase oxidation of model organic compound (ethanol) and compared with pelletized commercial Co-Mn-Al mixed oxide catalyst (Astin 2-100, Czech Republic, Co:Mn:Al molar ratio of 4:1:1).
