Rezumat: This study is aimed at the preparation of homogeneous, nanostructured and high surface area titania doped with CeO2, ZrO2 and SnO2 mesoporous oxides. These materials are used as a host matrix of Cu0.5Zn0.5Fe2O4 ferrite nanoparticles. The obtained composites are characterized by a complex of physicochemical techniques, such as nitrogen physisorption, XRD, SEM, HRTEM, Temperature – programmed reduction with hydrogen, XPS, UV-Vis and Moessbauer spectroscopies. Their catalytic behavior is tested in methanol decomposition as a source of hydrogen and total oxidation of ethyl acetate as a representative volatile organic compound. A synergistic activity between the acidic sites on the mixed oxide surface and the redox transitions in the hosted on them ferrite nanoparticles is well established. This effect is in a complex dependence on the surface and texture characteristics of the mesoporous TiO2-MO2 host matrix. The catalytic properties in both catalytic processes are optimized using mesoporous TiO2-CeO2 mixed oxide as a support of the Cu0.5Zn0.5Fe2O4 ferrite nanoparticles.
