Special rutile titanium dioxide (TiO 2 ) hollow microspheres were prepared successfully through hydrothermal methods when tetrabutyl titanate was adopted as raw material, β ‐cyclodextrin as template agent and polyvinylpyrrolidone as auxiliary agent. The effect of the concentration of hydrochloric acid and the temperature on the formation of TiO 2 morphology was discussed and the structure of the powders confirmed by Fourier transform infrared (FT‐IR), X‐ray diffraction (XRD), scanning electron microscopy and transmission electron microscope. The colour of products changed from black to white after roasted, and the results of FT‐IR and XRD measures showed its structure conforming to the rutile TiO 2 . It was found that the TiO 2 powders were hollow microspheres, and its surface tightly wrapped by nanorods for uniform, smooth, and orientation rule, which was of larger specific surface area.
