Facile Fabrication of Taper-Like BiVO₄ Nanorods with High Photocatalytic Property under Sunlight Irradiation

Abstract:

We report the synthesis of the taper-like BiVO4 nanorods by employing a solid-state grinding synthetic strategy. The X-ray diffraction (XRD) indicates that the as-prepared BiVO4 nanorods were crystallized in a monoclinic system. The diameter and length of taper-like nanorods are confirmed by the scanning electron microscopy (SEM) technology. The diameter and length of the taper-like nanorods are 100 nm and 1 μm, respectively. And the photocatalytic activity of the taper-like BiVO4 nanorods was evaluated by measuring the degradation of methylene blue (MB) in water under sunlight irradiation. MB was degraded nearly to nothing under sunlight irradiation for 120 min at room temperature in air. These results indicate the as-prepared product is a good sun-driven photocatalyst. In addition, the degradation mechanism of methylene blue over BiVO4 nanorods was tentatively investigated.

Facile Synthesis and Photocatalytic Performance of W₁₈O₄₉ Nanorods

Authors: Shuo Wang, Xia Xia Bai, Hui Zhang

Abstract: W₁₈O₄₉ nanorods photocatalyst was successfully synthesized by a facile pyrolyzing ammonium metatungstate in a reductive atmosphere of H₂ (5 vol %)/Ar. The synthesized W₁₈O₄₉ nanorods were characterized by X-ray diffraction (XRD), Raman spectrum, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and ultraviolet-visible (UV-Vis) absorption spectroscopy. The results show that W₁₈O₄₉ nanorods are about 190 nm in diameter and around 4.8 μm in length, and they possess the band-gap energy of 2.32 eV. Moreover the photocatalytic activity of W₁₈O₄₉ nanorods was evaluated by degrading methylene blue (MB) under visible light irradiation. The result illustrates that the W₁₈O₄₉ nanorods have a photodegradation efficiency of 60% for MB under the irradiation of xenon lamp (250 W, λ > 420 nm) for 2 h.

Synthesis and Photocatalytic Properties of the Bi₂MoO₆ and Bi₂WO₆ Photocatalysts

Authors: Juan Xia, Lin Zhang, Qi Wang

Abstract: Two different Bi-based semiconductor photocatalysts Bi₂MoO₆ and Bi₂WO₆ were synthesized by a simple one-pot hydrothermal reaction at 453 K for 10 h. The properties of the photocatalysts, including structures, morphology, light-absorption band and photoluminescence, etc were characterized by X-ray diffraction, scanning electron microscopy, UV-Vis diffuse reflectance spectrum and fluorescence spectrum. Further, their photocatalytic properties were compared by the degradation of two different organic dyes: Rhodamine B and methylene blue. It is important to note that the Bi₂WO₆ nanoplate structure exhibited better photocatalytic activity than the Bi₂MoO₆ nanowires aggregates due to its high surface area, higher light absorption and lower recombination of electron-hole pairs.
