  Titania and tungsten doped titania thin films on glass; active photocatalysts

  摘要：

  Acidification of an isopropanol solution containing mixtures of [Ti(OPri)(4)] and [W(OEt)(5)] produced solutions from which various TiO2, WO3 and TiO2/WO3 thin films could be obtained by dip coating and annealing. The films were analysed by X-ray diffraction, SEM/EDAX, Raman, electronic spectra, contact angle and photoactivity with respect to destruction of an over layer of stearic acid. The TiO2/WO3 films were shown to be mixtures of two phases TiO2 and WO3 rather than a solid solution TixWyO2. The 2% tungsten oxide doped titania films were shown to be the most effective photocatalysts. All of the TiO2 and TiO2/WO3 films showed light induced superhydrophillicity.

• Photocatalytic Activity of W-Doped TiO₂ Nanofibers for Methylene Blue Dye Degradation

  Photocatalytic degradation of methylene blue (MB) in water was examined using W-doped TiO2 nanofibers prepared by a sol-gel derived electrospinning and subsequent calcination for 4 h at 550 degrees C. Different concentrations of W dopant in the range of 0 to 8 mol% were synthesized to evaluate the effect of W concentration on the photocatalytic activity of TiO2. XRD results indicated that the undoped TiO2 is composed of anatase and rutile phases. The rutile phase was transformed to anatase phase completely with the W doping. Among W-TiO2 catalysts, the 2 mol% W-TiO2 catalyst showed the highest MB degradation rate. The degradation kinetic constant increased from 1.04 x 10(-3) min(-1) to 3.54 x 10(-3) min(-1) with the increase of W doping from 0 to 2 mol%, but decreased down to 1.77 x 10(-3) min(-1) when the W content was 8 mol%. It can be concluded that the degradation of MB under UV radiation was more efficient with W-TiO2 catalysts than with pure TiO2.

  Tungsten oxide coatings are chemically vapor deposited on polycarbonate via aerosol assisted at 125 degrees C. The effect of the Ar:O-2 ratio on the structural, morphological and electrochemical properties of the samples is investigated. The coating grown using Ar:O-2 ratio of 50:50, exhibits the best electrochemical activity and the fastest colouration-bleaching response. At the same time it offers a high specific capacitance that does not degrade upon at least 1000 successive charging-discharging cycles as studied by voltammetry in a solution of 1 M LiClO4. The importance of morphology towards the enhancement of the electrochromic behaviour of the coatings is discussed. (C) 2012 Elsevier Ltd. All rights reserved.
• Tunable Localized Surface Plasmon Resonances in Tungsten Oxide Nanocrystals

  Transition-metal oxide nanocrystals are interesting candidates for localized surface plasmon resonance hosts because they exhibit fascinating properties arising from the unique character of their outer-d valence electrons. WO3-delta nanoparticles are known to have intense visible and near-IR absorption, but the origin of the optical absorption has remained unclear. Here we demonstrate that metallic phases of WO3-delta nanoparticles exhibit a strong and tunable localized surface plasmon resonance, which opens up the possibility of rationally designing plasmonic tungsten oxide nanoparticles for light harvesting, bioimaging, and sensing.
