  XES, XPS and NEXAFS studies of the electronic structure of cubic MoO1.9 and H1.63MoO3 thick films

  摘要：

  X-ray emission spectroscopy (XES), X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) methods were used to study the electronic structure of cubic MoO1.9 and H1.63MoO3 thick films. For comparison, the orthorhombic form of molybdenum trioxide, MoO3, was also studied. XP valence-band and Mo 3d and O 1s core-level spectra, O Kalpha emission bands and NEXAFS O 1s spectra were measured. Half-widths of both the XP valence-bands and O Kalpha emission bands decreases in the sequence cubic H1.63MoO3 --> orthorhombic MoO3 --> cubic MoO1.9. The XPS and NEXAFS data reveal that the charge states of oxygen atoms do not change in the above sequence of compounds. The formation of an additional near-Fermi sub-band is characteristic for the XP valence-band spectra of cubic MoO1.9 and H1.63MoO3. The XES measurements indicate that the energy positions of maxima and of the centers of gravity of the O Kalpha bands remain constant within accuracy of the experiment for all the compounds studied.

  Physical and catalytic properties of hydrogen molybdenum bronze, H1.55MoO3 varied markedly with H2 reduction. The surface area was enlarged from 10 m2/g to 250 m2/g by H2 reduction at 673–723 K. H1.55MoO3 became an active and selective catalyst for pentane isomerization after reduction. H2-reduced H1.55MoO3 exhibited a comparable isomerization activity to H2-reduced Pt/MoO3.

  Reduction of ammonium molybdate, (NH4)6Mo7O24·4H2O, with hydroxylamine hydrochloride. NH2OH·HCl, at ambient temperature in aqueous solutions results in amorphous MoO3·nH2O oxide. Subsequent heat treatment of this oxide yields Mo1−δO2 or a hydrogen molybdenum bronze, HxMoO3 (x≅1), both crystalline in nature. The samples have been characterized by X-ray diffraction, differential scanning calorimetry

  The delithiated oxides, Li/sub 2-x/MoO/sub 3/ (O < less than or equal to 1.5) retain the parent ordered rocksalt structure. Complete removal of lithium from Li/sub 2/MiO/sub 3/ using Br/sub 2/ in CH/sub 3/CN results in a poorly crystalline MoO/sub 3/ that transforms to the stable structure at 280/sup 0/C. Li/sub 2/MiO/sub 3/ undergoes topotactic ion-exchange in aqueous H/sub 2/SO/sub 4/ to yield a new

  结果表明，在室温下使用 Br/sub 2/ 在 CHCl/sub 3/ 中可以从 Li/sub 2/MoO/sub 3/ 中氧化提取锂。脱锂氧化物 Li/sub 2-x/MoO/sub 3/ (O < 小于或等于 1.5) 保留了母体有序的岩盐结构。在 CH/sub 3/CN 中使用 Br/sub 2/ 从 Li/sub 2/MiO/sub 3/ 中完全去除锂导致结晶性差的 MoO/sub 3/ 在 280/sup 0/ 转变为稳定结构C。Li/sub 2/MiO/sub 3/ 在 H/sub 2/SO/sub 4/ 水溶液中进行拓扑离子交换，生成新的质子化氧化物 H/sub 2/MoO/sub 3/。

  Orthorhombic bronze, H0.30MoO3, was decomposed by vacuum heating to MoO2.86 With a rhombic MoO3 structure. The surface area increased slightly with the increase in the rhombic structure in which vacancies were produced. An approximate linear relationship was found between the catalytic activity of 1-butene isomerization and the hydrogen content(x) in the samples which were treated in air at 65 °C or

  正交青铜，H0.30MoO3，通过真空加热分解成具有菱形MoO3结构的MoO2.86。随着产生空位的菱形结构的增加，表面积略有增加。在 65°C 空气中或 220°C 以下真空处理的样品中，发现 1-丁烯异构化的催化活性与氢含量 (x) 之间存在近似线性关系。另一方面，220°C 以上的活性随着空位的形成而增加。

  In this letter a new synthetic strategy has been established for MoO 3 nanobelts by oxidizing Mo powders with H 2 O 2 in neutral water at 70 °C and a subsequent hydrothermal treatment at 140 °C. By introducing alcohol into this system, we can selectively prepare blue H x MoO 3 nanobelts. The photoluminescence (PL) property can be greatly altered before and after hydrogen incorporation into MoO 3 nanobelts

  在这封信中，通过在 70 °C 的中性水中用 H 2 O 2 氧化 Mo 粉末并随后在 140 °C 进行水热处理，为 MoO 3 纳米带建立了一种新的合成策略。通过将酒精引入该系统，我们可以选择性地制备蓝色 H x MoO 3 纳米带。在将氢掺入 MoO 3 纳米带之前和之后，光致发光 (PL) 特性会发生很大变化。纳米带形成过程的机制也得到了解决。
