Preparation of TiO2 fibers with well-organized structures

Abstract

Ceramic textiles and wools consisting of micrometersized TiO 2 hollow ®bers with porous walls were prepared by a chemical solution deposition technique using TiF 4 aqueous solutions.

Thermal evaporation growth and the luminescence property of TiO2 nanowires

“…O'Regan and Gratzel reported the application [2,3] of a low-cost, high-efficiency solar cell based on dye-sensitized colloidal TiO 2 films. The main reasons for the excitement over the TiO 2 materials are their interesting properties of catalysis, chemical inertness and non-toxicity [4][5][6][7][8] and so on. Therefore, numerous efforts have been devoted to applications in areas such as photocatalysts, gas sensors, environmental cleanup and high efficiency solar cells [9,10].…”

Photocatalytic degradation of eleven microcystin variants and nodularin by TiO2 coated glass microspheres

“…Three main ways of deploying TiO2 as a semi-conductor photocatalyst in water treatment have been examined. The materials have been deployed as (nanoparticulate) powders, as pellets, or as films attached to appropriate substrates [11][12][13]. Powders generally perform well in the photocatalytic degradation of organic compounds due to their large surface area and effective distribution in suspension.…”

Micrometer‐to‐Nanometer Replication of Hierarchical Structures by Using a Surface Sol–Gel Process

“…These biological tem- Figure 1.

“…There is quite a list of biological species that have been used as templates for the formation of porous inorganic structures, which includes bacterial superstructures, [8] cotton/cloth textile, [9] diatoms, [10] dog and human hair, [11] insect wings, [7] living cells, [12] mushroom gills, [11] plant leaves, [7] paper, [13] pollen grains, [14] shell membrane, [15] silk fiber, [11] skeletal plates, [16] spider silk, [7,11] wood, [17] and wool. [9] Scanning electron microscopy (SEM) images of a titania replication of cloth, a silica replication of a butterfly wing, and a silica replication of pine wood are shown as examples in Figure 1.
