Anodic TiO2 nanotube: influence of annealing temperature on the photocatalytic degradation of carbamazepine

Recent advances in anodically fabricated amorphous TiO2 nanotubes crystallization techniques and their applications

“…The direct influence of the phase composition of TiO 2 on photocatalytic degradation has been observed. The blend of anatase (80%) and rutile (20%) demonstrated a composition that resulted in a significant level of photocatalytic activity [36][37][38].…”

Phase Transformation Strategies for the Construction of Heterojunction TiO2 Photocatalysts

“…Therefore, rutile TiO 2 has higher stability, and the increases of temperature contribute to the formation of rutile. [88] In the report of Ding and his coworkers, [89] the TiO 2 nanobelt with anatase/rutile heterophase junction was synthesized by a hydrothermal/calcination treatment. Figure 2 distinctly dem-onstrates that only the characteristic peak of anatase is shown at low calcination temperatures.…”

“…According to the third item of Pauling rule, it is more stable with less common edges between coordination polyhedrons in a coordination structure. Therefore, rutile TiO 2 has higher stability, and the increases of temperature contribute to the formation of rutile [88] . In the report of Ding and his coworkers, [89] the TiO 2 nanobelt with anatase/rutile heterophase junction was synthesized by a hydrothermal/calcination treatment.…”

Crystallization of amorphous anodized TiO2 nanotube arrays

“…[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. 7,8 TiO 2 exhibits three common phase structures, with the anatase phase primarily used in catalysis and electrochemical applications, while the rutile phase nds applications in high-temperature coatings, optical devices, and more.…”
