Preparation of Nanosized Anatase Titania
Source abstract
Abstract
Nanosized anatase titania colloid and powders were prepared by hydrolysis of titaniumtetrabutoxide in basic media and then dehydrated at 700C in acid media. The powder and colloid were characterized by XRD、 BET、 TEM、 HREM and TG-DTA methods. The results show that after dehydrated in acid media the titania particles in colloid are already anatase crystallites with good crystal lattices. The average diameter of the nanosized titania powder after calcination at 220℃ is 9nm and surface area is 171m~2/g.
