    Metatungstate and tungstoniobate-containing LDHs: Preparation, characterisation and activity in epoxidation of cyclooctene
    摘要:
    Polyoxometalates (POMs) H2W12O406- and W4Nb2O194- have been intercalated between the brucite-like layers of Mg, Al and Zn, Al hydrotalcites by anion exchange, starting from the corresponding nitrate precursors. The solids have been characterised by Powder X-ray Diffraction (PXRD), Fourier Transform infrared (FT-IR) spectroscopy, N-2 adsorption-desorption at -196 degrees C and thermogravimetric (TG) and differential thermal analyses (DTA), and have been tested in the epoxidation of cyclooctene using H2O2 or t-BuOOH as oxidants. The results show that both anions are effectively located in the interlayer space maintaining their pristine structures without depolymerisation. Upon intercalation of such large anions microporosity is developed and subsequently an increase in the specific surface 06areas is also observed. In general, the prepared materials possess catalase and epoxidation activity, with ZnAl-intercalated H2W12O406- giving the best results in terms of epoxide yield (17% at 24 h). Product selectivity is different for the intercalated and free POMs, the latter yielding 1,2-cyclooctanediol as the only product, whereas the former produces only the epoxide. The epoxidation reaction seems to be catalysed in homogeneous phase by the POM. (c) 2007 Elsevier Ltd. All rights reserved.

    日期:1996.5
    synthetic method of tungstate thin films (CaWO4, MgWO4, PbWO4, ZnWO4) was developed. The absorption and luminescence spectra of tungstate thin films synthesized on quartz substrates were measured; the optical properties were also studied. It was found that CaWO4 has Eg = 5.4 eV of a direct transition nature. Tungstate thin films were strongly luminescent when irradiated with UV-light. Excitation at around

    On the Chemical Vapor Transport of Ternary Transition Metal- and Earth Alkaline Tungstates MWO4 with Chlorine The chemical vapor transport of transition metal tungstates MWO4 (M=Mn, Co, Ni, Cu, Zn, Cd) was investigated in dependence on mean transport temperature (923 K to 1223 K) and amount of transport agent Cl2. All tungstates migrate in a temperature gradient ΔT = 100 K from the region of higher

    DOI:10.1021/ic4031798
    日期:2014.5.5
    Using a combination of UV–visible spectroscopy and electronic structure calculations, we have characterized the electronic structures and optical properties of AWO4 (A = Mn, Co, Ni, Cu, Zn, or Mg) tungstates with the wolframite structure. In MgWO4 and ZnWO4, the lowest energy optical excitation is a ligand to metal charge transfer (LMCT) excitation from oxygen 2p nonbonding orbitals to antibonding
    通过结合紫外可见光谱和电子结构计算,我们表征了具有黑矿结构的酸盐4(A = Mn,Co,Ni,Cu,Zn或Mg)的电子结构和光学性质。在MgWO 4和ZnWO 4中,最低能级的光激发是从氧2p非键轨道到反键W 5d轨道的属电荷转移(LMCT)激发的配体。这两种化合物中LMCT跃迁的能量对于ZnWO 4是3.95 eV,对于MgWO 4是4.06 eV。。对于其他化合物,观察到的电荷转移能量要小得多,落在光谱的可见光范围内,范围为2.3至3.0 eV。在这些化合物中,A 2+离子的部分占据的3d轨道充当HOMO,而不是O 2p轨道。最低的能量电荷转移激发现在变成属间电荷转移(MMCT)激发,其中电子从A 2+离子的占据3d轨道转移到未占据的反键W 5d状态。由于由Cu 2+的d 9构型驱动的晶体结构变形,CuWO 4的MMCT值为2.31 eV最低。降低晶体对称性至三斜晶系的离子

    Abstract The subsolidus phase relations of the ZnO–P 2 O 5 –WO 3 ternary system were investigated by means of X-ray diffraction (XRD). No ternary compound was found in this ternary system, while five binary compounds were obtained and six compatibility triangles were determined.
