| 英文摘要 | Nanosized titania was prepared at various hydrolysis ratios (r = H-2/Ti) by photo-assisted and conventional sol-gel methods. It was found that hydrolysis ratio and ultraviolet irradiation greatly affect the titania crystallization behavior. The introduction of photo-irradiation benefits anatase formation throughout a wide range of hydrolysis ratio. XPS results show that hydrolysis reaction was promoted by ultraviolet irradiation. In addition, photo-irradiation was also verified to be in flavor of the generation of large specific surface area and high crystallinity, which resulted in relative high photocatalytic activity of TiO2 prepared by a photo-assisted sol-gel method.
