- Abstract
- Titania-incorporated silica (TiO2-SiO2) porous materials have great applications in diverse areas. In this work, TiO2-SiO2 porous materials with tunable Si/Ti molar ratio (R) have been successfully prepared through a one-pot method under a near-neutral condition. With decreasing Si/Ti R, a phase transition from a macroporous foam-like structure to mesostructure is observed. The resultant TiO2-SiO2 porous materials possess large surface areas and high pore volumes. In addition, the titania species are homogenously dispersed in silica matrix when Si/Ti R a parts per thousand yen 10. Our contribution provides a convenient method to synthesize TiO2/SiO2 porous materials with very large pore size, high pore volume, and relatively high titania content well dispersed in the silica wall framework.
