Titanium oxide nanoribbons

Reinforcement of flowable dental composites with titanium dioxide nanotubes

“…They concluded that hydrothermal reaction temperature of 100-160°C results in nanotube formation, whereas higher temperature of 180-250°C leads to formation of nanoribbons. Ribbon-like structures were obtained from hydrothermal reactions at 200°C [104]. Our results are in agreement with these results.…”

Titanate Nanotubes and Nanorods Prepared from Rutile Powder

“…This is slightly larger than that reported by Yuan et al for nanoribbons. [21] In addition to the increase in the nanotube content in the reaction product and an increase in the degree of their crystallinity, we observed that the average outside diameter of the nanotubes nearly doubled (from 8 nm in HTDO-100 to 15 nm in HTDO-150) when the hydrothermal treatment temperature was increased from 100 to 150 C. Therefore, the hydrothermal treatment temperature is a key parameter that influences the nucleation and crystal growth of the nanotubes. The change in the morphology, size, and crystal structure of the reaction product from nanotubes to nanorods at the higher hydrothermal temperature of 180 C reveals an alternative low-temperature mechanism for the formation of TiO 2 nanorods using metal± organic chemical vapor deposition (MOCVD).…”

“…These include the use of porous anodic alumina (PAA) as a template, and the use of supramolecular assemblies in a sol±gel polymerization process. [18] The nanostructures reported to date include TiO 2 nanowires, [19,20] nanoribbons, [21] nanotubes, [22±26] and lamellae. [27] Kasuga et al [22,23] reported a wet-chemical synthesis, in which TiO 2 powder or a TiO 2 ±SiO 2 mixture were treated first with NaOH solution and then with dilute acid solution.…”

Solvothermal Synthesis, Characterization, and Formation Mechanism of a Single‐Layer Anatase TiO2 Nanosheet with a Porous Structure

“…[20,21] Most of the reported TiO 2 nanosheets have been prepared through an alkaline hydrothermal process by using TiO 2 powder as precursor, or prepared from protonic titanate hydrates by either calcination or hydro/solvothermal reactions, and show a single-crystalline structure. [22,23] There are, however, only very few reports [20] on the fabrication of two-dimensional polycrystalline TiO 2 nanosheets with porous and high-surface areas arising from the assembly of nanoparticles as the building blocks; these structures are potentially useful as catalysts and may act as SERS substrate and active components in fabricating gas sensors.…”
