We report experimental results on the kinetics of the electron-beam-induced reduction of WO, by in situ high-resolution electron microscopy. Electron-beam irradiation of WO, results in complete reduction to W. The process is surfaceinitiated through desorption of oxygen from the crystal surface, and the subsequent growth of tungsten was found to be a diffusion-controlled process. The damage rat...

A two-step procedure was implemented to obtain tungsten oxide nanowires (WO3) doped with cobalt or silver oxide nanoparticles from metal-organic precursors, W(CO)6, Co(acac)2 and Ag(acac)2. In the first step, nanowires were grown at 400 °C using an aerosol assisted chemical vapor deposition system (AA-CVD) and subsequently annealed at 500 °C for 2 h. In the second step, metal loading (at differ...

Tungsten trioxide (WO3) films have been coated on indium thin oxide (ITO) conductive glass substrate, using aqueous solution of peroxotungstic acid (PTA) by the sol-gel dip coating method. X-ray diffractometery (XRD) analysis confirmed monoclinic and triclinic structure for the film and powdered WO3 respectively. Fourier transforms infrared spectroscopy (FT-IR) exhibit...

UV-visible diffuse reflectance spectroscopy was used to probe the electronic structure and domain size of tungsten oxide species in crystalline isopolytungstates, monoclinic WO3, and dispersed WOx species on ZrO2 surfaces. UV-visible absorption edge analysis, CO2 chemisorption, and Raman spectroscopic results show that three distinct regions of WOx coverage on ZrO2 supports appear with increasi...

We prepared a series of sodium phosphate glasses by changing WO3/P2O5 content and investigated structure optical radiation shielding features as function the glass composition. The average density ( $$\rho_{{{\text{exp}}}}$$ )was found to increase gradually from 2.49 3.07 g/cm3, while molar volume values reduced 47.37 44.28 cm3/mol with WO3 addition. Also, field strength was also computed incre...

Advanced photocatalysts that can utilize solar energy for water purification applications are always needed. The present article reports a facile fabrication of tungsten oxide (WO3)/bismuth oxychloride (BiOCl) immobilized on polyaniline (PAn) (BiOCl/WO3@PAn) heterojunction nanocomposite photocatalyst. designed nanocatalyst was tested 2-chlorophenol (2-CP) decontamination from the aquatic system...
