Abstract

Nanocrystalline rutile TiO₂ with average crystal sizes of 6.9–10.5 nm and specific surface areas of 70.3–141.0 m²g⁻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.
