Abstract

The fabrication of mesoporous titania (MPT) nanofibers by using a bimodal templating concept, an amphiphilic triblock copolymer template within a porous alumina template, was discussed. The X-ray diffraction (XRD) diffraction patterns for the MPT nanofibers in small-angle and wide-angle regions were also shown. It was shown that the resulting MPT nanofibers consist of nanocrystalline anatase titania, and the pore can be easily controlled with the utilized amount of titania precursor. The transmission electron microscope (TEM) images reveal that the MPT nanofibers have a mesoporous structure with a wormlike nanochannel network inside of the nanofibers and the wall frameworks consists of nanocrystalline titania with a crystal size if 3-8 nm.
