description In this paper, the effect of the support on the catalytic behavior of CuFe<sub>2</sub>O<sub>4</sub> mixed oxides, supported on ZSM-5 and Al<sub>2</sub>O<sub>3</sub>, for a ferrite/support relation of 30%, is analyzed. The supported Cu ferrite was obtained by impregnation of the supports with Cu and Fe nitrates solutions and adding citric acid, for calcination temperatures between 150 and 700ºC. The propane combustion was used as reaction test. The catalytic activity was determined in a fixed bed flow reactor at programmed temperature, with a flow of 100 cm<sup>3</sup>/min containing a mixture of oxygen 4% and propane 1000 ppm. The addition of 500 ppm of NO in the feed resulted in different effects in the reaction. The zeolitic catalysts demonstrated to be active for the reduction of NO to N<sub>2</sub>,as well as for the oxidation of propane to CO<sub>2</sub>. The ferrite supported on Al<sub>2</sub>O<sub>3</sub> only showed activity for the propane oxidation to CO<sub>2</sub>. For both materials, the propane conversion, in presence of NO in the feed, is shifted towards lower temperatures suggesting that the hydrocarbon activation is modified by the presence of NO.
