Diffusion during electron-beam-induced reduction of tungsten trioxide
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...
متن کاملIonic liquid-modulated preparation of hexagonal tungsten trioxide mesocrystals for lithium-ion batteries.
Hexagonal (h-WO3) mesocrystals with biconical morphology were prepared by a straightforward ionic liquid-assisted hydrothermal route and investigated as anodic materials for lithium-ion batteries. Compared to the alternatives, the biconical tungsten trioxide mesocrystal exhibited excellent lithium insertion with good cyclability and rate capability, making it a promising candidate as the anode ...
متن کاملPhotocatalysis and Photoelectrochemical Properties of Tungsten Trioxide Nanostructured Films
Tungsten trioxide (WO₃) possesses a small band gap energy of 2.4-2.8 eV and is responsive to both ultraviolet and visible light irradiation including strong absorption of the solar spectrum and stable physicochemical properties. Thus, controlled growth of one-dimensional (1D) WO₃ nanotubular structures with desired length, diameter, and wall thickness has gained significant interest. In the pre...
متن کاملPolaron mobility in oxygen-deficient and lithium-doped tungsten trioxide
Electron localization and polaron mobility in oxygen-deficient as well as Li-doped monoclinic tungsten trioxide have been studied in the adiabatic limit in the framework of density functional theory. We show that small polarons formed in the presence of oxygen vacancy prefer the bipolaronic W5+-W5+ configuration, whereas the W6+-W4+ configuration is found to be metastable. Our calculations sugg...
