Enhanced electron collection in photoanode based on ultrafine TiO2 nanotubes by a rapid anodization process

TiO2 nanotube structures for the enhancement of photon utilization in sensitized solar cells

“…This would lead to the existence of large voids and the poor attachment and connectivity of aggregates, affecting the dye loading and electron transport. As a result, the solar cells based on pure NT powder showed inferior performances [151,152].…”

Nanoscale TiO2 films and their application in remediation of organic pollutants

“…Thus, smaller TiO 2 particles which possess dramatically higher surface-to-volume ratio, have greater specific surface area available for catalysis. As such, TiO 2 catalysts have been prepared in various nano-forms such as mobilized (nanoparticle powders [65], nanowires [79], nanotubes [32,80,81], and nanorods [82,83] in suspension form) and immobilized states (as thin films) [3,28,37,[84][85][86][87], with each having its own advantages and disadvantages. For example, as nanopowder mobilized form, TiO 2 has high photocatalytic activity because of its large available sur-A c c e p t e d M a n u s c r i p t Edited June 15 7 face area for photocatalysis [27,88].…”

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].…”
