Monocomponent and bicomponent iron and/or titanium modified MCM-41 materials prepared by direct synthesis at room temperature were investigated using X-ray diffraction (XRD), nitrogen physisorption, UV-Vis diffuse reflectance, FT-IR and Mössbauer spectroscopy. Their catalytic behavior was studied in cylohexanol conversion. Materials with high surface area and well-ordered pore structure were obtained. All modified mesoporous silicas possess high activity in cyclohexanol conversion. Bicomponent FeTiMCM-41 catalyst pretreated in hydrogen at 723 K presented the highest activity and selectivity to cyclohexanone.
