Abstract

Uniform and thermally stable spherical titania particles with hollow interiors were directly prepared by a novel solvothermal precipitation of TiCl4 in isopropanol without templates or shape-controller reagents. An average particle size of 700 nm to 1 μm was obtained. The hollow spheres consisted of pure anatase phase nanocrystals with an estimated crystallite size of 12–15 nm. Upon heating, the pure anatase phase was retained for temperatures up to 800 °C, which suggested that the spherical structure contributed to phase stability. This method is a promising process for industrial-scale preparation of titania hollow spheres.
