Abstract: 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-Emrnett-Teller analysis (BET). The crystalline structure of the as-synthesized nanofibers demonstrated a layered titanate form, H[subscript 2]Ti [subscript x]O[subscript 2x+1]. The length of the prepared nanofibers ranged from 2 to 7 (mu)m with diameters ranging from 20 to 90 nm. The as-synthesized nanofibers were solids with BET surface areas of approximately 50 m[superscript 2]/g. This synthetic method provides a simple route for the fabrication of one-dimensional (I-D) nanostructured materials from a low-cost natural mineral.
