Preparation and Polymorphic Transition of Nanosized Y-doped TiO2
Abstract:
Nanosized TiO2 and Y-doped TiO2 were synthesized from Ti(OC4H9)4 and Y(NO3)3 by a sol-gel method. The structure, size, appearance, and the polymorphic transition between anatase and rutile of TiO2 crystal types were examined by XRD, TEM, TG-DTA. The results indicate the average particle size of TiO2 crystal is about 30 nm and the doped Y prevents the transition of TiO2 from anatase to rutile.
