Preparation and characterization of porous titania by modified sol-gel method

Mesoporous titania, especially anatase, is attractive due to its potential applications. A novel method to control pore structure of titania, surfactant- or polymer modification, is proposed. The wet gels and gel films, prepared from Ti(O-nC4H9)4 were dried at 90°C and annealed at 500°C after immers...
