TiO2 nanorods can be used as dye-sensitized solar cells and as various sensors and photocatalysts. These nanorods are synthesized by a using thermal corrosion process in a NaOH solution at 200 oC with TiO2 powder as a source material. In the present work, the synthesis of TiO2 nanorods in anatase, rutile and Ti8O15 phases and the synthesis of TiO2 nanorods by using the sol-gel method and alkaline corrosion to incorporate aluminum oxide dopant are reported. The morphologies and the crystalline structures of the TiO2 nanorods are characterized using field emission scanning electron microscope (FE-SEM), atomic force microscope (AFM), and X-ray diffraction (XRD) techniques.
