Long TiO2 Hollow Fibers with Mesoporous Walls:  Sol−Gel Combined Electrospun Fabrication and Photocatalytic Properties

Long TiO2 Hollow Fibers with Mesoporous Walls:  Sol−Gel Combined Electrospun Fabrication and Photocatalytic Properties

Long TiO2 hollow fibers with mesoporous walls have been fabricated with the sol−gel combined two-capillary spinneret electrospinning technique using a triblock copolymer (Pluronic, P123, (H(C2H5O)20(C3H7O)70 (C2H5O)20OH) as a pore-directing agent. The as-prepared hollow fibers were as long as 30 cm...

description Long TiO2 hollow fibers with mesoporous walls have been fabricated with the sol−gel combined two-capillary spinneret electrospinning technique using a triblock copolymer (Pluronic, P123, (H(C2H5O)20(C3H7O)70 (C2H5O)20OH) as a pore-directing agent. The as-prepared hollow fibers were as long as 30 cm with an outer diameter of 0.1−4 μm and wall thickness of 60−500 nm. The diameters and wall thicknesses of the hollow fibers could be tuned by adjusting the electrospinning parameters. The fiber walls were composed of mesopores 6.7 nm in diameter as calculated from the N2 adsorption/desorption isotherm. The high-resolution TEM (HR-TEM) images exhibited that the mesopores were hexagonally aligned with a low order because of the curving of the pores. When comparing with other nanostructured TiO2 materials such as commercial TiO2 nanoparticles (P25, Degussa) and mesoporous TiO2 powders, the hollow fibers exhibited higher photocatalytic activities toward degradation of methylene blue and gaseous formaldehyde.
