【Abstract】 Monodispersive nanosized titanium oxide (TiO2) catalyst can be successfully prepared via assembling based on the nanosized pore structure. Technologies such as rearrangement of layered silicates, hydrothermal synthesis under alkalescence system, room temperature synthesis in acid system and microwave method are introduced. Processes and properties of mesoporous assembling nanosized TiO2 by direct synthesis, hydrothermal synthesis, sol-gel, impregnation and hydrolysis are primarily summarized. Development prospect in this field is also pointed out.更多还原
