Abstract

Cobalt and iron modified MCM-41 and SBA-15 materials were prepared by incipient wetness impregnation technique and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), N 2 physisorption, temperature-programmed reduction (TPR-TGA), UV-Vis diffuse reflectance and Mössbauer spectroscopy. Formation of finely dispersed ferrite and cobalt-oxide species was observed on MCM-41 and SBA-15 supports. It was found that the surface properties of the mesoporous support and the temperature of precursor decomposition determine the type of formed metal oxides, their dispersion, reducibility and the catalytic activity in total oxidation of toluene.
