The role of the synthetic procedure on the photoactivity of nanocrystalline TiO2

Ardizzone S., Bianchi C.L., Cappelletti G., Pirola C., Ragaini V., University of Milan, IT

The nanometer scale of the TiO2 plays a key role in affecting the photocatalytic performance of the material. In recent years a great deal of activity was dedicated, by the authors, to the study of [...]

Titanium Dioxide Nanostructured Coatings: Application in Photocatalysis and Sensors

Byrne J.A., Hamilton J.W.J., McMurray T.A., Dunlop P.S.M., Donaldson V.J.A., Rankin J., Dale G., Al Rousan D., University of Ulster, UK

This paper presents results concerning the fabrication, characterisation, and application of nano-structured titanium dioxide films. Applications include photocatalytic purification of water, “self-decontaminating” surfaces, and electrochemical biosensing.

Mimicking Photosynthesis to Make Functional Nanostructures and Nanodevices

Shelnutt J.A., Wang Z., Song Y., Medforth C.J., Pereira E., Sandia National Laboratories, US

Photocatalytic porphyrins are used to reduce metal complexes from aqueous solution and, further, to control the deposition of metals onto porphyrin nanotubes and surfactant assembly templates to produce metal composite nanostructures and nanodevices. For example, [...]
