Large-size mesoporous thin films with mixed titania-silica framework and Im3m cubic-derived or worm-like mesostructure were obtained by combining sol-gel and macromolecular templating techniques. These materials presented accessible mesopores (20-25% pore volume), tunable  refractive index and high molecular-scale mixing of both ions, as demonstrated by UVVisible, FTIR and XANES spectroscopy. In addition, a composition effect in the catalytic reduction of silver was found, which permitted to obtain homogeneous metal nanoparticle-mesoporous film anocomposites with tuned plasmon position.
