abstract = {Mn-Cu mixed oxides were deposited by ultrasonic impregnation on ceramic honeycomb
12 monoliths. Its catalytic performance was evaluated in the combustion of ethanol and n-hexane, VOC
13 molecules of different chemical nature. The catalysts were characterized by N2 physisorption, SEM14 EDS, XRD, X-ray fluorescence, XPS, TPR, TPD-O2 and OSC measurements. It was observed that
15 the catalyst with the lowest content of Mn-Cu phase was the most active in the combustion of
ethanol. This was attributed to the higher content of Mn4+ 16 and the increase of lattice oxygen mobility,
17 which would favor a Mars-van Krevelen type mechanism. The catalyst with a medium content of
18 Mn-Cu, proved to be the most active in the combustion of n-hexane. This was associated with a high
19 content of oxygen vacancies and easy availability of oxygen adsorbed on the surface, promoting the
20 combustion of n-hexane, possibly through a Rideal-Eley type mechanism. The catalyst with the
21 highest content of the Mn-Cu phase showed low activity in combustion of ethanol and n-hexane,
22 which was attributed to a higher crystallinity of the Mn-Cu phases generated.},
