    Mesoporous silica spheres were used as templates to prepare 5 to ∼10 nm Sn doped TiO2 (TDT) nanofibers using SnCl4 and TiCl4 as precursors. The as-made nanofibers were crystalline anatase but transformed into the rutile phase after annealing above 700 °C. The Sn dopant amount in the TDT nanofibers can be controlled by changing the molar ratio of SnCl4 to TiCl4.
