Resum
TiO2-WO3nanocomposites were prepared by colloidal processing in solvothermal conditions, with W:Ti nominal atomic ratio of 0.16 and 0.64. By exploiting the different chemical properties of the precursors, it was possible to separately nucleate TiO2 anatase nanocrystals and tiny species of W oxides. After heat-treatment at 500 °C, TiO2 nanocrystals with a size of about 8 nm were obtained, among which WO3 monoclinic nanocrystals were dispersed, as ensured by X-ray diffraction, High-resolution tra...
