The gas sensing properties at room temperature of TiO2 nanotubes by anodization

Application-wise nanostructuring of anodic films on titanium: a review

“…[51] Proposed low-temperature gas sensing mechanisms depend on the nature of gas À for instance, H 2 diffuses into a TiO 2 lattice acting as an electron donor [52] or forms OH groups at its surface, creating an electron-rich interface region while reducing gases tend to react with photogenerated ionised oxygen species produced on TiO 2 by UV irradiation…”

Effect of electrolyte age and potential changes on the morphology of TiO2 nanotubes

“…Since the first reports by Assefpour-Dezfuly in 1984 [1] and by Zwilling et al in 1999 [2], the formation of TiO 2 nanotubes by anodization of titanium has attracted significant attention due to the great application of the nanotubes in various fields, such as dye sensitized solar cells [3][4][5][6][7], sensors [8][9][10][11][12], photocatalysis [13][14][15], and biomedical applications [16][17][18]. For the first generation of nanotube arrays HF-containing electrolytes were employed [1,19,20].…”

INFLUENCE OF HIGHLY CONCENTRATED SODIUM HYDROXIDE (NaOH) TOWARDS FORMATION OF HIGHLY ORDERED TIO2 NANOTUBES (TNT) STRUCTURE

“…TNT is promising nanomaterial due to its high properties that suitable for various applications in fuel cell technology, solar cell, storage energy material [1] and also gas sensing properties [2]. TNT receives numerous attention in fuel cell technology as different roles for each type of fuel cell including as catalyst support for main catalyst [3][4][5][6], photocatalyst [7][8][9][10], gas sensor [2,11,12] and composite membrane [13,14]. For the synthesized method, TiO 2 nanotubes can be produced via three common methods: (i) electrochemical anodization, (ii) template assisted and (iii) hydrothermal method.…”
