Preparation of High Photocatalytic Activity Nano-crystalline Titanium Dioxide by High Temperature Thermo-Hydrolysis Method
Abstract:
Nano-crystalline titanium oxide(TiO2) was prepared by the high-temperature thermo-hydrolysis method and crystallized in organic media. Microcrystalline was characterized by TG-DTA, XRD, BET and TEM methods, the average diameter of this titanium dioxide is 12nm with the surface area greater than 100m2•g-1, and the crystal is of anatase structure over a relative wide temperature range. The photocatalytic activity of this titanium oxide was determinated by measuring the rate of degradation of methyl orange and the rate of formation of degradation product. The results showed that this titanium oxide has much higher photocatalytic activity.
