摘要：

Nanocrystalline rutile TiO2 with average crystal sizes of 6.9-10.5 nm and specific surface areas of 70.3-141.0 m(2)g(-1) were prepared by hydrolysis of TiCl4 aqueous solution at lower temperatures. The presence of small amounts of nano rutile TiO2 as crystal seed could obviously accelerate the crystallization of TiO2, make nanocrystalline rutile TiO2 well dispersed and make the reaction of formation of rutile more kinetically favorable than that of formation of anatase in the liquid hydrolysis of TiCl4.
