Photocatalytic activity of nanotubular TiO2 films obtained by anodic oxidation: a comparison in gas and liquid phase

Sanabria B.E., Strini A., Schiavi L., Diamanti M.V., Pedeferri M.P., Politecnico di Milano, IT

The immobilization of nanostructured photocatalysts is of great importance in the purification of both polluted air and liquids (e.g. industrial wastewaters). Titanium dioxide films with nanotubular morphology and good photocatalytic efficiency in both environments can [...]

Memristor fabrication and characterization based on TiO2

Diamanti M.V., Pisoni R., Cologni A., Corinto F., Pedeferri M.P., Politecnico di Milano, IT

Today, Si-based flash memory devices represent the most prominent nonvolatile data memory (NVM) because of high density and low fabrication costs. However, they suffer from low endurance, low write speed, and high voltages required for [...]

Advanced oxidation processes for water purification: compact vs nanoporous anodic TiO2

Piazza V., Diamanti M.V., Mazare A., Pedeferri MP., Schmuki P., Politecnico di Milano, IT

In the last years, research on TiO2 engineering has been dedicated mostly to thin films for environmental and energetic applications, such as advanced oxidation processes for water purification and dye-sensitized solar cells. Anodic oxidation can [...]

High photocatalytic activity of hydrogen production from water over Fe doped and Ag deposited anatase TiO2 nanotube arrays

Fan J., Fan X., Fan J., Fan X., Hu X., Liu E., Kang L., Tang C., Wu H., Li Y., Liu E., Ma Y., Northwest University, CN

Recently, studies revealed that noble metal (Au, Ag, Pd) nanoparticles can improve the photoresponse property of TiO2 in the visible region based on the localized surface plasmon resonance (LSPR) effect, and thus enhance the activity [...]
