  燃烧合成适用性的新标准：二元化学反应的热力学和动力学过程研究

  摘要：

  燃烧合成是一种利用化学反应的放热来维持反应并快速制备材料的新技术。但是，迄今为止，尚未提出用于验证燃烧合成的统一标准。在此，我们提出了需要满足的条件。就动力学而言，在绝热温度（T ad）下，原子的扩散距离（升Ť广告）在0.1 s内应大于反应物的粒径（d）， 那是， 升Ť广告≥d。对于满足T ad / T m，L的系统≥1（其中T m，L是反应物的低熔点成分的熔点），液相的存在将原子的扩散距离从纳米显着增加到数十微米，从而成为标准升Ť广告≥d简化为T ad / T m，L≥在大多数情况下为1。在热力学方面，系统需要确保反应成分处于激活状态，即T ad / T m，H ≥0.7，其中T m，H是高熔点组分的熔点。本研究提出的SHS反应标准进一步提高了对SHS反应的理论理解，并为探索二元和多组分化合物的超快合成提供了指导。

  具有成本效益的高性能 Ni3Sn4 电催化剂用于酸性环境中的甲醇氧化反应

  摘要：

  甲醇 (CH 3 OH) 氧化为向清洁能源过渡提供了一条有前途的途径，特别是在直接甲醇燃料电池 (DMFC) 领域。然而，开发高效且具有成本效益的甲醇氧化反应 (MOR) 催化剂仍然是一项严峻的挑战。在此，我们报告了 Ni 3 Sn 4的优异电催化活性和稳定性对酸性介质中的 MOR，实现与商业 Pt/C 催化剂相当的性能。我们的催化剂设计结合了地球上丰富的 Ni 和 Sn 元素，使材料的成本效益比 Pt/C 高 1800 倍。密度泛函理论 (DFT) 建模证实了我们的实验结果，揭示了 Ni 3 Sn 4表面上有利的反应机制和动力学。此外，合成后的 Ni 3 Sn 4电催化剂表现出值得称道的耐久性，即使在长时间暴露于苛刻的酸性条件下也能保持其电催化活性。

• Enthalpy of formation for CoGe, CoSn, Ni3.14Sn4, Ni3.50Sn4, AuCo1.66Sn4, AuNi2Sn4 and Au1.17Pt1.82Sn4

  The enthalpies of dissolution, H-diss, of CoGe, CoSn, Ni3.14Sn4, Ni3.50Sn4, AuCo1.66Sn4, AuNi2Sn4 and Au1.17Pt1.82Sn4 and their components have been measured in molten tin at 874 K by drop calorimetry. The enthalpy of formation of these phases, Delta H-f(298), has been derived for 298 K. Earlier measurements of the enthalpy of formation for the elements, disregarding cobalt, are in close agreement with the present results. The values for pure Co show significant temperature dependence, and also deviate from earlier findings. For the binary and ternary phases the accordance with earlier results for the Ni3 + vSn4 phase is perhaps acceptable when the differences in specimen compositions are taken into account. The corresponding comparison for CoGe and CoSn has a much poorer outcome. The latter discrepancies are tentatively coupled to distinctions between the species of dissolved cobalt in liquid tin at different temperatures. No enthalpy of formation measurements have been reported for any of the ternary phases. Comparison of theoretically computed data for the enthalpy of formation for the binary and ternary phases shows close agreement with the measured values obtained in this study.

  Enthalpies of formation (Delta H-f) of nickel-tin compounds have been measured by direct reaction calorimetry: Delta H-f(Ni3Sn2_LT) = -29.0 +/- 0.9 kJ mol(-1) (approximate value); Delta H-f(Ni3Sn2_HT) = -35.0 +/- 0.2 kJ mol(-1); Delta H-f(Ni3Sn2_HT) = -34.3 +/- 1.7 kJ mol(-1); Delta(f) H-Ni3Sn_HT = -21.0 +/- 2.4 kJ mol(-1); Delta(f) H-Ni3Sn_LT = -24.4 +/- 1.2 kJ mol(-1) and Delta H-f(Ni3Sn4) = -29.8 +/- 1 kJ mol(-1).Standard states are solid Ni and liquid. Sn at the respective working temperatures: 728, 1288, 1389, 1332, 943 and 846 K.The enthalpy of formation of the Ni3Sn high-temperature form is measured for the first time, while that of Ni3Sn2_LT must be considered as approximate because the corresponding calorimetric reaction was incomplete.The chemical and phase compositions of the specimens have been verified by electron probe microanalyses and by high- and room-temperature X-ray diffraction analyses. Unidentified thermal effects have been observed in the Ni3Sn2 phases region. (C) 2006 Elsevier B.V. All rights reserved.

  Standard enthalpies of formation were determined for a number of binary intermetallic compounds in the systems Ag-Sn, Cu-Sn, and Ni-Sn by means of solution calorimetry in liquid Sn in a Calvet-type microcalori meter. For the pure elements Ag, Cu, and Ni, the limiting partial enthalpies of mixing as well as the enthalpies of solution at infinite dilution in Sn were measured at 773, 873, 973 and 1073 K. The results for the enthalpy of formation for the intermetallic compounds Ag3Sn, Ag4Sn, Cu3Sn, Cu41Sn11, Cu6Sn5, Ni3Sn-LT, Ni3Sn2-HT, and Ni3Sn4 are discussed and compared with the corresponding literature values.
