Rhodamine B degradation efficiency of differently annealed titanium dioxide nanotubes

Diamanti M.V., Stercal F., Pedeferri MP., Politecnico di Milano, IT

This paper presents an investigation over the photoefficiency of nanotubular titanium dioxide films in the degradation of organic pollutants: rhodamine B was chosen as model reactant. The effects of thermal treatments in several atmospheres on [...]

Influence of pigments on the photoactivity of TiO2-containing colored mortars compared with white mortars and sol-gel TiO2 application route

Diamanti M.V., Del Curto B., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

In previous works, TiO2-containing commercial mortars were proved to show photoactivated properties due to the well-known semiconducting structure of titanium dioxide in anatase form. Anatase was added to white mortars in form of suspension or [...]

Morphological variations on titanium by AC anodizing

Diamanti M.V., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

Besides the widely investigated photoinduced properties of its oxides, a primary branch of application of anodized titanium is the production of biomedical implants, where a controlled roughness can lead to improvements in cell adhesion and [...]

Photoactive and coloured anodic oxides on titanium for architectural and design applications

Diamanti M.V., Del Curto B., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

Anodising processes can lead to the formation of oxides showing a wide range of interference colours with different hues and saturations depending on process parameters. The control of morphology, structure and homogeneity of the oxide [...]

Effect of thermal treatments on the structure of photoactive titanium oxides

Diamanti M.V., Codeluppi S., Cordioli A., Pedeferri MP., Politecnico di Milano, IT

Nanocrystalline TiO2 is one of the most important and used photocatalysts because of the excellent efficiencies of conversion of chemical species, and its chemical stability. Its photocatalytic properties are activated only by UV light; nevertheless, [...]
