    Titanate nanofibers were synthesized by a simple hydrothermal method using a natural ilmenite mineral as the starting material. The chemical composition, crystalline structure, shape, size, and specific surface area of the prepared samples were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and the Brunauer-Emmett-Teller analysis (BET). The crystalline structure of the as-synthesized nanofibers demonstrated a layered titanate form, H <inf>2</inf>Ti<inf>x</inf>O<inf>2x+1</inf>. The length of the prepared nanofibers ranged from 2 to 7 μm with diameters ranging from 20 to 90 nm. The as-synthesized nanofibers were solids with BET surface areas of approximately 50 m<sup>2</sup>/g. This synthetic method provides a simple route for the fabrication of one-dimensional (1-D) nanostructured materials from a low-cost natural mineral. © 2012 Elsevier Ltd and Techna Group S.r.l.
