High pressure synthesis of amorphous TiO2 nanotubes

TiO2 nanotubes: synthesis and applications.

TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulate...

Synthesis of oriented arrays of TiO2 nanorods via a high temperature conversion of carbon nanotubes.

Oriented arrays of both rutile and anatase nanorods have been synthesised in a two-stage process, employing multi-walled carbon nanotubes as the initial structural template.

High-pressure polymorphs of anatase TiO2

High-Pressure Study of Anatase TiO2

We report resistivity and thermo-electric power measurements of the anatase phase of TiO2 under pressure up to 2.3 GPa. Despite its transparent appearance, the single crystal of anatase exhibits a metallic-like resistivity above 60 K, at all pressures. The rather high value of the thermo-electric power at room temperature points to complex transport mechanism in this phase.

TiO2 Nanotubes: Recent Advances in Synthesis and Gas Sensing Properties

Synthesis--particularly by electrochemical anodization-, growth mechanism and chemical sensing properties of pure, doped and mixed titania tubular arrays are reviewed. The first part deals on how anodization parameters affect the size, shape and morphology of titania nanotubes. In the second part fabrication of sensing devices based on titania nanotubes is presented, together with their most no...
