Synthesis of Brookite-Typed Titania from Titanium Chloride Solution
The brookite-phase TiO2 was prepared by a hydrothermal synthesis of titanium chloride solution. The thermolysis time and the pH value of the solution were controlled during the synthesis. X-ray diffraction experiments showed that TiO2 powders partially containing the brookite-phase were successfully obtained. A higher amount of OH- in the reaction solution was found to be important to obtain the brookite phase because the intermediate complex leading to the brookite phase consumes more amount of OH- than other phases like the rutile.
