- A characterization of double oxide systems containing Cr$\text{}_{2}$O$\text{}_{3}$ doped with MgO and supported on MgF$\text{}_{2}$ was carried out. The catalysts were prepared by impregnation and co-impregnation methods and characterized by the Brunauer-Emmett-Teller method, EPR, and temperature programmed reduction. The results proved the interactions between supported oxides and the presence of spinel-like phase after treatment at 400ºC. Magnesium oxide clearly influences the catalytic activity as well as selectivity of chromium catalysts supported on MgF$\text{}_{2}$. The MgO-Cr$\text{}_{2}$O$\text{}_{3}$/MgF$\text{}_{2}$ systems were active and selective in the reaction of CO oxidation at the room temperature and in the dehydrogenation of cyclohexene.
