Incorporation of 12-Tungstophosphoric acid in Titania spheres and fabrication of core-shell Polyoxotungstate/Titania nanostructures
Core-shell 12-tungstophosphoric acid/TiO2 (HPW/TiO2) nanoparticles at 10 and 20% of HPW have been synthesized by simple in-situ sol- gel method. Characterization of the samples was carried out by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FTIR). The X-ray diffraction patterns of as prepared solid samples, indicated characterist...
متن کاملPhotocatalytic properties of titania nanostructured films fabricated from Titania nanosheets.
We examined the photochemical properties of well-ordered multilayer films of titania nanosheets prepared on quartz-glass substrate using the layer-by-layer deposition method. The photocatalytic decomposition of gaseous 2-propanol and bleaching of Methylene Blue dye under UV light illumination were measured to evaluate the photocatalytic oxidation ability. Photoinduced hydrophilicity was also st...

متن کاملCharacterization of titania silicalites
Titanium-substituted silicalites, prepared from two different silicalite precursors, are characterized using Raman spectroscopy, X-ray absorption spectroscopy, pyridine adsorption, and methanol oxidation. The silicalite precursors used are tetraethyl orthosilicate and Ludox AS 40. Two different types of titania species are observed in the titania silicalites. Below 1.6 mole% Ti/(Ti + Si), a dis...
