“…The specific surface area for very wide tubes is not very high except for the cases where the structure of the microtube wall contains small channels. [6] Nanotubes have potential uses in photocatalytic removal of organic pollutants or in solar cells, [12,13] although industrial applications may be limited by the cost of materials, insufficient material characterization, and concerns over long-term instability.…”

Tubular and fibrous nanostructures of titanates have recently been synthesized and characterized. Three general approaches (template assisted, anodic oxidation, and alkaline hydrothermal) for the preparation of nanostructured titanate and TiO2 are reviewed. The crystal structures, morphologies, and mechanism of formation of nanostructured titanates produced by the alkaline hydrothermal method are critically discussed. The physicochemical properties of nanostructured titanates are highlighted and the links between properties and applications are emphasized. Examples of early applications of nanostructured titanates in catalysis, photocatalysis, electrocatalysis, lithium batteries, hydrogen storage, and solar‐cell technologies are reviewed. The stability of titanate nanotubes at elevated temperatures and in acid media is considered.

“…The diffusion coefficient of an electron in the anatase TiO 2 nanoparticle film is several orders of magnitude lower than that in anatase TiO 2 single crystal, which limits the power conversion efficiency [6,7]. To increase the diffusion coefficient of the electrons and improve the charge transport, DSSCs using one-dimensional (1-D) structures of TiO 2 as electrodes, such as nanotubes, nanorods and nanowires, have been recently reported [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. These 1-D structures will enhance the electron transport due to the features of highly decreased particle to particle contacts and elongated structure with the specified directionality [12].…”

“…These 1-D structures will enhance the electron transport due to the features of highly decreased particle to particle contacts and elongated structure with the specified directionality [12]. Generally, these 1-D structures are made by chemical methods and a high temperature treatment is needed, which is not suitable for flexible DSSCs [13][14][15]17,18,20]. Magnetron sputtering technique has been considered as an adequate method for large area deposition with high uniformity at a relatively low deposition temperature.…”

TiO 2 nanorods were prepared by DC reactive magnetron sputtering technique and applied to dye-sensitized solar cells (DSSCs). The length of the TiO 2 nanorods was varied from 1 μm to 6 μm. The scanning electron microscopy images show that the nanorods are perpendicular to the substrate. Both the X-ray diffraction patterns and Raman scattering results show that the nanorods have an anatase phase; no other phase has been observed. (101) and the (220) diffraction peaks have been observed for the TiO 2 nanorods. The (101) diffraction peak intensity remained constant despite the increase of nanorod length, while the intensity of the (220) diffraction peak increased almost linearly with the nanorod length. These nanorods were used as the working electrodes in DSSCs and the effect of the nanorod length on the conversion efficiency has been studied. An optimum photoelectric conversion efficiency of 4.8% has been achieved for 4 μm length nanorods.

“…Electron transport in 1D structure is expected to be several orders of magnitude faster than in random network (Law et al, 2005;Zhu et al, 2007;Thavasi et al, 2009). Many works have been done for 1D structure based DSSC and the conversation efficiency is approaching that for 3D nanoparticles based DSSC (Adachi et al, 2004;Ngamsinlapasathian et al, 2004;Jiu et al, 2006;Lee et al, 2009;Ren et al, 2014;Sabba et al, 2014;Shao et al, 2014).…”

TiO 2 films have been deposited on ITO substrates by DC reactive magnetron sputtering technique. It has been found that the sputtering pressure is a very important parameter for the structure of the deposited TiO 2 films. When the pressure is lower than 1 Pa, the deposited film has a dense structure and shows a preferred orientation along the [101] direction. However, the nanorod structure has been obtained as the sputtering pressure is higher than 1 Pa. These nanorod structure TiO 2 films show a preferred orientation along the [110] direction. The phases of the deposited TiO 2 films have been characterized by the x-ray diffraction and the Raman scattering measurements. All the films show an anatase phase and no other phase has been observed. The results of the scanning electron microscope show that these TiO 2 nanorods are perpendicular to the ITO substrate. The TEM measurement shows that the nanorods have a very rough surface. The dye-sensitized solar cells (DSSCs) have been assembled using these TiO 2 nanorod films prepared at different sputtering pressures as photoelectrode. And the effect of the sputtering pressure on the properties of the photoelectric conversion of the DSSCs has been studied.
