Large-pore mesoporous titania-silica thin films (Ti1-xSixO2, 0.1 ≤ x ≤ 0.9) with highly interdispersed mixed oxide frameworks
Large-size mesoporous thin films with a mixed titania-silica framework and an Im over(3, -) m cubic-derived or worm-like mesostructure were obtained by combining sol-gel and macromolecular templating techniques. These materials presented accessible mesopores (20 to 25% pore volume), tunable refracti...
