Optimized Nanostructured TiO2 Photocatalysts
Titania is the most widely studied photocatalyst. In its mixed-phase configuration ( anatase–rutile form) – as manifested in the commercially available P25 Degussa material – titania was previously found to exhibit the best photocatalytic properties reported for the pure system. A great deal of published research by various workers in the field has not fully explained the underlying mechanism f...
متن کاملNanostructured TiO2 thin films as porous cellular interfaces
We report the use of nanostructured TiO2 (NST) as porous cellular adhesion interfaces for microsystems. Integrated NST films and pad arrays with sponge-like morphology were fabricated by aqueous oxidation of Ti films followed by thermal annealing. Cell culture studies indicate significantly (t < 0.02 from the student’s t-test) greater initial attachment of mouse fibroblast cells on porous NST t...
متن کاملPhotoinduced absorption spectroscopy of dye-sensitized nanostructured TiO2
Photoinduced absorption (PIA) spectroscopy was used to investigate dye-sensitized electrodes and solar cells under illumination conditions comparable to sunlight. In the absence of redox electrolyte, cis-RuðdcbpyÞ2ðNCSÞ2-sensitized nanostructured TiO2 films show a long-lived photoinduced charge-separation (oxidized dye molecules/injected electrons in TiO2), with a lifetime of about 10 3 s under...
متن کاملFabrication of Nanostructured Tio2 Surfaces for Photocatalytic Applications
This paper presents titanium dioxide nanostructured surfaces prepared in organic electrolytes containing ammonium fluoride by anodic oxidation method. Two approaches were used for fabrication, one-step and two-step anodization. The obtained TiO2 surfaces have nanoporous structure. The morphology of anodized TiO2 nanostructures was characterized by scanning electron microscopy (SEM).
متن کاملNanostructured TiO2 architectures for environmental and energy applications
Semiconductor photocatalysts have important applications in the fields of renewable energy and environmental remediation. Of these, TiO2 stands out as one of the most investigated compounds in contemporary material science. Because of its unique physical and chemical properties, TiO2 is extensively used in photoelectrochemical applications including photocatalysis and photovoltaics. In this Rev...
