Abstract: In this study, Co-Mn-Al mixed oxides modified by K were prepared by co-precipitation of a solution of metal nitrates with the aqueous solution of K2CO3 and KOH, washing the precipitates to different level of K concentrations and finally calcined at chosen temperature, usually 500 °C. The catalysts were characterized by AAS, nitrogen physisorption (Sbet), TPR-H2, XRD, and TPD- CO2. In case of direct NO decomposition, the catalysts pre-calcined at 700 °C were tested for direct NO decomposition in inert gas (650 °C, 0.5 g, 1000 ppm NO/N2, 49 ml min"1). Deep oxidation of ethanol was carried out under following conditions: 0.2 g, 760 ppm of ethanol in air, 4 000 ml h'1, the temperature ramp of 2 °C min'1.
