  双络合物盐[PdL4] [RuNO（NO2）4OH]（L = NH3，Py）的合成，结构及双金属亚稳态固溶体Pd0.5Ru0.5的制备

  摘要：

  摘要制备了两种含[RuNO（NO2）4OH] 2-阴离子和[PdL4] 2+阳离子（L = NH3，Py）的双络合物盐，并用红外光谱，单晶和粉末XRD对其进行了描述。两种化合物的晶体结构均由复杂的钯阳离子和复杂的钌阴离子组成。在[Pd（NH3）4] [RuNO（NO2）4OH]阳离子和阴离子被NH3和NO2配体之间的氢键结合的情况。在惰性和还原性气氛下检查了盐的热分解。两种络合物都在几个阶段分解，根据IR光谱的第一阶段包括阴离子的OH基团的裂解，进一步的分解经历了NH 3和NO 2配体的去除。在[Pd（NH3）4] [RuNO（NO2）4OH]的情况下，还原性气氛中热分解的最终温度为250–270°C，最终产物对应于亚稳的Pd0.5Ru0.5固溶体。通过XRD和EDX数据确认了金属固溶体的组成。检查了制备的固溶体的电化学和催化性能。

  However, Pd–Ru nanoparticle (NP) alloys are rarely reported so far, owing to the limitations described by Hume‐Rothery. Herein, we successfully synthesized Pd–Ru NP alloys over the whole composition range using a facile atomic‐diffusion‐based strategy, and we carefully investigated the corresponding formation mechanism. For the first time, we confined the size of all alloy NPs at 3–5 nm, which is

  Pd和Ru都是电化学中的重要元素。然而，由于休姆-雷特里（Hume-Rothery）所描述的局限性，迄今为止，极少报道Pd-Ru纳米粒子（NP）合金。在这里，我们使用一种基于原子扩散的策略成功地合成了整个组成范围内的Pd-Ru NP合金，并仔细研究了相应的形成机理。我们首次将所有合金纳米颗粒的尺寸限制在3-5 nm，这在直接甲酸燃料电池中是有利的。实验数据表明，由于电子从Pd转移到Ru，Pd的核心能级结合能正向移动。这种电子效应可以有效地调节电催化过程中反应性分子的吸附强度。在所有这些影响的驱使下，这些Pd-Ru合金具有很高的活性，并且对甲酸氧化稳定。组成-活性研究进一步表明，Pd60 Ru 40表现出最好的质量活性，是商业Pd / C的4.1倍。

  Double complex salts (DCSs) with [M(NH3)(5)Cl](2+) (M = Rh, Ir, Co, Cr, Ru) cations and [PtBr4](2-) anions were prepared in high yields. The salts were two-phase mixtures of the anhydrous and monohydro DCSs. Anhydrous analogues containing [PdBr4](2-) anions with M = Cr or Ru were synthesized. All the compounds were characterized using a set of physicochemical methods. The crystal structure of chloropentaamminechromium(III) tetrabromopalladate(II) was solved: space group Pnma, Z = 4, a = 17.068(2) angstrom, b = 8.315(12) angstrom, c = 9.653(14) angstrom. The [M(NH3)(5)Cl][M'X-4] (M = Rh, Ir, Co, Cr, Ru; M' = Pd, Pt; X = Cl, Br) compounds were shown to be isostructural. The [M(NH3)(5)Cl][PtBr4] center dot H2O monohydrates are isostructural to the [M(NH3)(5)Cl][PdCl4] center dot H2O monohydrates (space group P2(1)/c, z = 4). The properties of the compounds were comparatively analyzed. The tendencies of the thermal stability of the complexes were elucidated. The thermolysis products of the double complex salts obtained under a helium or hydrogen atmosphere were studied.

  PdxRu1-x solid solution alloy nanoparticles were successfully synthesized over the whole composition range through a chemical reduction method, although Ru and Pd are immiscible at the atomic level in the bulk state. From the XRD measurement, it was found that the dominant structure of PdxRu1-x changes from fcc to hcp with increasing Ru content. The structures of PdxRu1-x nanoparticles in the Pd composition range of 30-70% consisted of both solid solution fcc and hcp structures, and both phases coexist in a single particle. In addition, the reaction of hydrogen with the PdxRu1-x nanoparticles changed from exothermic to endothermic as the Ru content increased. Furthermore, the prepared PdxRu1-x nanoparticles demonstrated enhanced CO-oxidizing catalytic activity; Pd0.5Ru0.5 nanoparticles exhibit the highest catalytic activity. This activity is much higher than that of the practically used CO-oxidizing catalyst Ru and that of the neighboring Rh, between Ru and Pd.
