Abstract

Pure rutile TiO₂ nanorods are fabricated using TiCl₃ as the predecessor at 180°C for 24h. TiO₂ nanomaterials turn into pure anatase when KF serves as mineralizer and the concentration of KF solution is higher than a proper concentration. It is indicated that the fluorin-ion has a great effect on the phase transition of TiO₂ crysta1. The length and diameter of nanocrystal granules also change when changing the concentration of KF solution. The anatase TiO₂ nanocrystals are synthesized at 150°C for 24h with TiCl₃ and titanate sodium nanotubes as the predecessors at the filling factor of 68%.
