Improved osseointegrating functionality of cell sheets on anatase TiO2 nanoparticle surfaces

TiO2 anatase nanoparticle networks: synthesis, structure, and electrochemical performance.

Nanocrystalline anatase TiO(2) materials with different specific surface areas and pore size distributions are prepared via sol-gel and miniemulsion routes in the presence of surfactants. The samples are characterized by X-ray diffraction, nitrogen sorption, transmission electron microscopy, and electrochemical measurements. The materials show a pure anatase phase with average crystallite size ...

Photocatalytic oxidation surfaces on anatase TiO2 crystals revealed by single-particle chemiluminescence imaging.

We report a single-particle approach for studying the photocatalytic oxidation reaction on individual anatase TiO(2) particles. Single-particle kinetic and imaging analyses of the chemiluminescence (CL) emitted from the probe dye molecules revealed that the oxidation reactivity is not significantly dependent on the crystal faces.

Enhanced photocatalysis by coupling of anatase TiO2 film to triangular Ag nanoparticle island

In order to overcome the low utilization ratio of solar light and high electron-hole pair recombination rate of TiO2, the triangular Ag nanoparticle island is covered on the surface of the TiO2 thin film. Enhancement of the photocatalytic activity of the Ag/TiO2 nanocomposite system is observed. The increase of electron-hole pair generation is caused by the enhanced near-field amplitudes of loc...

High-pressure polymorphs of anatase TiO2

Band alignment of rutile and anatase TiO2

The most widely used oxide for photocatalytic applications owing to its low cost and high activity is TiO2. The discovery of the photolysis of water on the surface of TiO2 in 19721 launched four decades of intensive research into the underlying chemical and physical processes involved2–5. Despite much collected evidence, a thoroughly convincing explanation of why mixed-phase samples of anatase ...
