Treatments with water and diluted nitric acid were made to the support alumina, used to prepare supported manganese oxides catalysts. The different supports and the resulting catalysts were characterized by techniques as BET, pore volume distribution, XRD, TPD-NH3, FTIR, TPR, XFR, XPS and Zeta Potential. As the treatments results, modifications of the support physicochemical properties were observed. Catalytic performance was evaluated in ethanol combustion. The most active catalyst were those prepared from the treated supports, using a manganese monolayer. XPS and Zeta Potential.
