In this work, titanium dioxide (TiO2) nanofibers were obtained from anodic oxidation process. A piece of titanium sheet was anodized in 1.0M sodium chloride (NaCl) solution, at 30 V. The as-anodized sample was calcinated at 400 degrees C for one hour. Subsequently the sample was characterized using field-emission scanning electron microscopy (FE-SEM), high resolution X-ray diffraction (HR-XRD), and Raman spectroscopy. Interestingly, results showed rutile phase dominates over anatase phase, which is rarely reported. In addition, the possible chemical reactions that lead to the formation of nanofibers were proposed. It was found that the nanofibers having an average length of 3 mu m, also diameter of 83 nm. (C) 2011 Elsevier B. V. All rights reserved.
