Synthesis and analysis of TiO2 nanotubes by electrochemical anodization and machine learning method for hydrogen sensors

Review—Recent Progress in the Design of Chemical Hydrogen Sensors

“…6. 71 Anodizing titanium foils at 20 °C in a solution of 0.5% and 1% (wt) ammonium fluoride resulted in the synthesis of TiO 2 nanotubes. The nanotubes exhibited amorphous, rutile, and anatase phases following annealing at temperatures of 700 °C and 300 °C.…”

Synthesis of TiO2 Nanotubes and Photodiode Performance

“…However, the diameters of the tubes were not formed in the same dimensions. In order for the tube diameters to be the same, parameters such as anodization temperature, application voltage, application time can be optimized [23]. (1) where I0 is the saturation current found given by;…”

Crystallization of amorphous anodized TiO2 nanotube arrays

“…Its advantages, such as non-toxicity, high chemical stability, and excellent biocompatibility, have led to widespread research in catalysis, sensors, dye-sensitized solar cells, electrochemical energy storage, and biomedical elds. [1][2][3][4][5] In comparison to randomly oriented nanostructures, the ordered arrangement of TiO 2 nanotube arrays (TNTAs) has attracted considerable attention due to its high surface area, porosity, and excellent electron transport properties. 6 TNTAs are typically prepared directly on titanium substrates using the anodization method, which is a straightforward approach allowing for the fabrication of vertically aligned and highly ordered nanotube array.…”
