Hollow TiO 2 fibers with a high surface area were prepared by a simple manufacturing method using Ceiba pentandra (L.) Gaertn. (kapok) as a natural biomass template. Heat treatment was used for the removal of the kapok template. The uniform morphology of the hollow TiO 2 fibers with an average diameter of 10μm was investigated by field emission scanning electron microscopy (FE-SEM). In spite of the micrometer size of the hollow TiO 2 fibers, the walls had a high surface area (143m 2 /g) and a high pore volume (0.21cm 3 /g), as determined by Brunauer–Emmett–Teller (BET) analysis. Calcination was found to promote the crystalline transformation of TiO 2 , as evidenced by X-ray diffraction (XRD).
