Photocatalytic Activity of Immobilized Nano-TiO2 in Complex Wastewaters: Case Study of Multiple Dye Composition

Bellè U., De Flaviis L., Diamanti M.V., Ormellese M., Pedeferri M., Politecnico di Milano, IT

Titanium dioxide (TiO2) is widely investigated for its photocatalytic properties and for the possibility of obtaining nanotubular oxide films with high specific surface area directly immobilized on a substrate. In the present work, nanotubular TiO2 [...]

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 [...]

Thermostability of TiO2 nanoparticle and its Photocatalytic Reactivity at Different Anatase/Rutile Ratio

Tseng Y-H, Lin H-Y, Kuo C-S, Li Y.Y., Lin H-Y, Huang C.P., Industrial Technology Research Institute, TW

Thermostability study of commercial P25 TiO2 nanoparticles was carried out by ascending annealing temperature from 400 to 1100 oC. The thermostability of TiO2 structure was measured by X-ray diffraction (XRD). Anatase-Rutile phase transition occurred only [...]

Development of a New Treatment to Induce Anatase Growth on Ti

Pedeferri M., Bottani C.E., Cattaneo D., Li Bassi A., Del Curto B., Brunella M.F., Politecnico di Milano, IT

Aim of the work has been the evaluation of the application of a novel treatment of the Ti surface in order to increase anatase growth. Two different anodizing methodologies, previously developed were considered, followed by [...]
