Titanium dioxide nanotube array film

Surface-leveled TiO2 nanotube array films were prepared by optimized anodization techniques. The film can be used not only for photocatalysis, dye-sensitized solar cells, energy storage materials, etc., but also as a template to prepare more complex materials and structures.

Characteristics, appearance
The thickness of TiO2 substrate is 300um, which is prepared by anodizing method. The nanotubes have the characteristics of one end opening, ordering and single layer.
The product has not been heat treated, so the prepared TiO2 nanotube array does not exhibit a specific crystal structure, is amorphous, and has no obvious Raman peak.
Heat treatment is an important step to optimize the performance of TiO2 nanotubes. Appropriate heat treatment can reduce the grain boundary energy, eliminate amorphous components, and effectively improve quantum efficiency. After annealing at 400oC, obvious Raman peaks appear at 145 nm, 398 nm, 515 nm, and 638 nm. At this time, the TiO2 nanotube array exhibits an anatase phase structure; after annealing at 600 °C, the TiO2 nanotubes The array will show a new Raman peak at 614 nm, which belongs to the Raman peak of the TiO2 rutile phase. At this time, the TiO2 nanotube array has two phases of anatase phase and rutile phase.
