The Hydrothermal Synthesis and Photocatalysis of TiO2 Powders
Titania powders were prepared under hydrothermal conditions by employing organic molecule β-cyclodextrin(CD) as template, and characterized by means of TGA、XRD、BET . The effects of the pH on the specific surface area and photocatalytic performance of titania were discussed. The results showed that titania powders were anatase structure;the titania powders with specific surface area up to 216.2 m2g-1 were prepared while the system pH was about 1 , and the powders had the best photocatalytic activity.
