A series of titania modified mesoporous silica (Ti-SBA-15) with various Ti/Si mole ratios were prepared by sol-gel method from tetraethoxysilane (TEOS) and titanium ethoxide. In this work, Poly(ethylene oxide-b-propylene oxide-b-ethylen oxide) was used as a surfactant to make highly ordered mesoporous materials by templating. The samples were characterized by small angle x-ray scattering (SAXS), N-2 adsorption-desorption measurement (BET), and FT-IR spectroscopy.
