Abstract:

Films of bismuth and nickel tungstates were obtained by chemical and electrochemical synthesis. Bismuth tungstate was obtained by ionic layering and electrochemical deposition. Nickel tungstate (NiWO4) was obtained by combined synthesis methods: 1st - electrochemical synthesis and 2nd - combined electrochemical and thermochemical synthesis. The obtained materials have good adhesion with an optically transparent SnO2 substrate. It is shown that the mechanism of electrochemical formation of Bi2WO6 and NiWO4 films is similar to the processes of WO3 formation as a result of electroreduction of per

GdFe3(BO3)4, single crystals were grown from melt-solutions based on bismuth trimolybdate and lithium tungstate. Single crystals of gadolinium ferroborate from lithium-tungstate solution-melt were grown for the first time. The magnetic properties of the grown crystals are compared. It is shown that the GdFe3(BO3)4, ferroborate obtained using bismuth solution-melt trimolybdate contains impurities of Bi3+ ions (6% at.), which replace Gd3+ ions. Whereas GdFe3(BO3)4, ferroborate grown from a solution-melt based on lithium tungstate does not seem to contain such uncontrolled impurities. Keywords: c

In this work, a new morphology was obtained for bismuth tungstate (Bi2WO6-glyc) using a hydrothermal method with the addition of glycerol as a surfactant.

A rich structural polymorphism was revealed. At P ≃ 3.5 GPa a phase transition from the initial orthorhombic phase of P21 ab symmetry to an orthorhombic phase of B2cb symmetry was observed. This transition is caused by the complex spatial rotation of the WO6 octahedra.

The development of active and stable photocatalysts for the degradation of volatile organic compounds under visible light is important for efficient light utilization and environmental protection. Titanium dioxide doped with nitrogen is known to have a high activity but it exhibits a relatively low stability due to a gradual degradation of nitrogen species under highly powerful radiation. In this paper, we show that the combination of N-doped TiO2 with bismuth tungstate prevents its degradation during the photocatalytic process and results in a very stable composite photocatalyst.

The prepared nanoparticles were investigated by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), UV-visible spectroscopy and dielectric studies. The formation of Bi2WO6nanoparticles was confirmed by X-ray diffraction (XRD). The morphology of Bi2WO6nanoparticle was characterized using scanning electron microscopy SEM. The optical properties were studied by the UV-Visible absorption spectrum. The dielectric properties of Bi2WO6nanoparticles were studied. The activation energy was calculat

Abstract:

The BiOCl and Bi2WO6 successfully used the cyclic microwave method at 450 W. The structure, morphology, and optical properties were analyzed using X-ray diffraction (XRD), electron microscopy (SEM), transmission electron microscopy (TEM), and UV-visible spectrophotometer. The impact of dye treatment from photocatalytic synthesis, with and without pH adjustment, was also examined. It was discovered that the pH adjustment of the Bi2WO6 photocatalyst improved the treatment of MO dyes to 91% removal after 80 minutes. Additionally, the ability of the photocatalyst to treat other dyes, such as rhoda

Abstract:

Bismuth tungstate (Bi2WO6) microcrystalline with different surfactant were successfully prepared by a facile hydrothermal route.The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and BrunauerEmmettTeller surface area (BTE) in detail. The photocatalytic activity of the samples was also evaluated using the degradation of Rh B at room temperature under visible light irradiation. It was found that the surfactant played important roles in the formation process of controlling the morphology and structure of the catalyst and also had a great influence on th

Abstract:

Bismuth-based oxides have attractive photocatalytic properties under visible light. Bismuth tungstate(Bi2WO6) particles as a visible light-responsive photocatalyst were prepared by a facile hydrothermal reaction method with the different surfactant assisted using Bi(NO3)3·5H2O and Na2WO4 as raw materials at 180°C for 24h. The as-prepared samples were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-vis absorption spectra (UV-vis). The photocatalytic activity of Bi2WO6 crystals was evaluated using the photocatalytic oxidation of rhodamine B (RhB) at room tem
