Synthesis of titanium containing periodic mesoporous organosilica

摘要：

Organic-inorganic mesostructured materials were functionalized with titanium by direct synthesis under strong acidic conditions using non-ionic surfactants as structure directing agent and titanocene dichloride as titanium precursor. Materials with different organic content were synthesized with a high mesoscopic order and with incorporation of titanium species in isolated framework positions. The physicochemical properties of the synthesized samples were assessed by different characterization techniques including XRD, 29Si MAS-NMR, nitrogen adsorption/desorption experiments, and DR UV-VIS spectroscopy. These materials with enhanced hydrophobic properties could have interesting applications in the liquid-phase epoxidation of olefins with organic hydroperoxides.
