The influence of the template extraction method and the Ti content on the textural and structural characteristics of Ti-MCM-41 materials is reported. The synthesized solids were characterized by N2 physisorption, XRF, XRD, HREM, FT-Raman and UV-vis. diffuse reflectance spectroscopy (DRS). Between the two methods used to remove the surfactant, the application of polar solution (0.05 M H2SO4 in ethanol) resulted to be more efficient reducing the destruction of mesoporous material during the calcination step. The samples prepared by this method demonstrated more ordered hexagonal pore structure (HREM, XRD) with higher values of specific surface area and pore volume. The order of hexagonal arrangement of pores in Ti-MCM-41 materials and their textural characteristics (SBET and total pore volume) descease with the TiO2 content indicating that it is possible to incorporate isomorphically into the MCM-41 framework during the synthesis only small amounts of TiO2.
