Formation of 8nm TiO2 nanotubes on a three dimensional electrode for enhanced photoelectrochemical reaction

A novel Bi 2 S 3 nanowire @ TiO 2 nanorod heterogeneous nanostructure for photoelectrochemical hydrogen generation

“…Among them, TiO 2 is of http://dx.doi.org/10.1016/j.cej.2016.05.126 1385-8947/Ó 2016 Elsevier B.V. All rights reserved. particular interest due to its chemical stability, low cost, excellent electrical property and well-developed synthetic methods [23][24][25]. However, TiO 2 is a wide bandgap semiconductor (E g % 3.2 eV) and can only absorb and utilize the ultraviolet region of the solar spectrum [26,27].…”

Morphology-controllable polycrystalline TiO2 nanorod arrays for efficient charge collection in dye-sensitized solar cells

“…Recently, TiO 2 has been intensively studied in various fields such as solar cells [1][2][3][4][5][6][7][8][9][10], photocatalysis [11][12][13][14][15][16][17][18], lithium batteries [19][20][21][22] and sensors [23,24], because they are photoelectrochemically active, highly stable and environmentally benign etc. By different preparation ways, TiO 2 could be tailored into nanostructures with diverse geometries, including nanotubes [25], nanowires [26], nano-flowers [27], nano-tapes [28] and so on, which would further modify the properties of TiO 2 [29].…”

Comparison of Photoelectrochemical Current in Amorphous and Crystalline Anodized TiO2 Nanotube Electrodes

“…Titanium dioxide (TiO 2 ) has been used in various applications such as biomedical devices, solar cells, and photodegradation [1][2][3][4]. TiO 2 nanotubes (NTs), in particular, are utilized due to their tube-like configuration that exhibits high surface area, relatively short conduction path [3,5], and biocompatibility [4,6].…”

“…The exposure of TiO 2 nanotubes to ultraviolet radiation produces highly oxidative holes and weakly reductive electrons [10]. Recent studies have measured the photoelectrochemical activity of anatase TiO 2 [3]. However, only a few studies have been conducted to determine the possible use of an amorphous TiO 2 as a source of these charges and as the medium for charge transport.…”
