Synthesis and Characterization of Anatase and Rutile Titania Nanorods by Sol~Electrophoretic Deposition

In this paper one-dimensional nano structured titania was grown in polycarbonate template with diameter about 200 nm using sol electrophoretic deposition method. The structure, morphology, phase composition, and chemical bands of Ti02 nanorod arrays were characterized by scanning electron microscopy (FESEM), X-ray diffraction (XRD) and infrared spectroscopy (FT-IR). FE-SEM images showed that these aligned nanorods with length of 10 jim were dense and continuous with a uniform diameter of about 180 nm throughout their entire length. Moreover, X-ray diffraction analysis revealed that the Ti02 nanorods contained of anatase phase after drying at 100gC, while they were crystallized in the anatase and rutile phases after annealing to 500 eC for 1 hour.
