  Mono-disperse MMoO3·2H2O (M=Mn, Co, Ni) compound nanocrystals: Syntheses, characterization and luminescent properties

  摘要：

  Mono-disperse MMoO(3)(.)2H(2)O (M = Mn, Co, Ni) compound nanocrystals were synthesized by a low-temperature hydrothermal reaction route using (N2H4H2O)-H-. as a reduction reagent as well as a structure-directed reagent. The physical characterizations were carried out by TGA, XRD, XPS, SEM and Photo RE The data of XRD indicate a single phase of monocline symmetry. Nanostructures of MMoO3.2H(2)O (M = Mn, Co, Ni) samples in zero, one or two dimensions were observed from SEM images, respectively. Furthermore, MMoO3-2H(2)O are luminescent, which is different from composite oxides with ordinary structure. (c) 2006 Elsevier B.V. All rights reserved.

  Ni2 Mo3 N上的表面氧化物富集活化层（SOAL），用于快速且持久的放氧反应。

  摘要：

  氧气释放反应（OER）是可再生能源技术的关键，例如水电解和金属空气电池。但是，与质子偶联的电子转移相关的多个步骤会导致OER动力学下降，因此需要催化剂。在这里，我们证明了一种新型的氮化物Ni 2 Mo 3 N是一种高活性的OER催化剂，其性能优于基准材料RuO 2。Ni 2 Mo 3 N在0.1 m的额定超电势为270 mV时 表现出10 mA cm -2的电流密度KOH具有出色的催化循环性和耐久性。结构表征和计算研究表明，出色的活性源自表面富氧化物活化层（SOAL）的形成。表面上的次级Mo原子充当电子泵，稳定含氧物质并促进反应的连续性。这一发现将刺激具有氧化物表面层的三元氮化物作为电化学能量装置的有效OER催化剂的进一步发展。

  Abstract The efficient synthesis of polycrystalline filled beta-Mn structured Ni2Mo3N, and the eta-carbides Fe3Mo3N and Co3Mo3N, by a single heating of metal powders at 975 °C under a hydrogen-nitrogen mixture is reported. Rietveld analysis of high-resolution X-ray powder diffraction data shows that the reduction-nitridation of NiMoO4 produces Ni2Mo3N and nickel; Ni3Mo3N is not obtained in this way

  摘要 报道了通过在 975 °C 下在氢-氮混合物下对金属粉末进行单次加热，有效合成了多晶填充的 β-Mn 结构的 Ni2Mo3N 以及 eta-碳化物 Fe3Mo3N 和 Co3Mo3N。高分辨率 X 射线粉末衍射数据的 Rietveld 分析表明，NiMoO4 的还原氮化生成 Ni2Mo3N 和镍；Ni3Mo3N 不是这样得到的，它的存在被否定了。

  A reduced or partially reduced nickel-molybdenum catalyst prepared by a process having the steps of 1) reacting nickel carbonate and molybdenum oxide precursors to form nickel molybdate and 2) treating the nickel molybdate under reducing conditions to form the reduced or partially reduced nickel-molybdenum catalyst. There is also a process for making the catalyst. There is also a process for using the catalyst in the hydrogenation of an oxo aldehyde, thereby forming an oxo alcohol of high selectivity. There is also a process for forming an oxo alcohol from the hydroformylation/hydrogenation of an olefinic feedstream. There is also a process for forming an oxo alcohol by contacting formates, dimers, trimers, and organic acids with hydrogen in the presence of a reduced or partially reduced nickel-molybdenum catalyst. The foregoing processes are also useful with a catalyst having the general formula Y x Z wherein Y is nickel and/or cobalt and Z is molybdenum and/or tungsten; and wherein x ranges between about 0.25 to about 4.0. There are also reduced or partially reduced catalysts of the general formula Ni x Mo or Y x Z wherein x ranges between about 0.25 to about 4.0 and wherein oxide precursors of the catalysts are substantially free of ammonium groups.

  Single crystal structure determination shows that these compounds are constructed from infinite chains consisting of edge-shared octahedral cluster units. The structure can be viewed as a stacking along the c axis of layers consisting of parallel chains, with the chains in successive layers oriented alternately along the a and b axes.

  Coexisting phases in the Ni-Mo-O ternary system at 1373 K have been identified by X-ray diffraction, optical microscopy and scanning electron microscopy. The samples were equilibrated in evacuated quartz capsules. Only one ternary phase, NiMoO4, was found to exist in the system. The reversible e.m.f. values of the following solid-state galvanic cells were measured in the temperature range 900 to 1500
