Abstract
Titania-incorporated silica (TiO
2
–SiO
2
) porous materials have great applications in diverse areas. In this work, TiO
2
–SiO
2
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 TiO
2
–SiO
2
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
≥ 10. Our contribution provides a convenient method to synthesize TiO
2
/SiO
2
porous materials with very large pore size, high pore volume, and relatively high titania content well dispersed in the silica wall framework.
