  A benign route to fabricate nanoporous gold through electrochemical dealloying of Al–Au alloys in a neutral solution

  摘要：

  Nanoporous gold (NPG) ribbons have been fabricated through electrochemical dealloying of melt-spun Al-Au alloys with 20-50 at.% Au in a 10 wt.% NaCl aqueous solution under potential control at room temperature. The microstructures of NPG were characterized using X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray (EDX) analysis. The microstructures of the NPG ribbons strongly depend upon the phase constitutions of the starting Al-Au alloys. The single-phase Al2Au or AlAu intermetallic compound can be fully dealloyed, resulting in the formation of NPG with a homogeneous porous structure. The separate dealloying of Al2Au and AlAu in the two-phase Al-45 Au alloy leads to the formation of NPG composites (NPGCs). In addition, the dealloying of the Al-20 Au alloy comprising alpha-Al and Al2Au leads to the formation of NPG with bimodal channel size distributions. According to the ligament size, the surface diffusivity of Au adatoms along the alloy/electrolyte interface has been evaluated and increases with increasing applied potential. The dealloying mechanism in the neutral NaCl solution has been explained based upon pourbaix diagram and chloride ion effect. (C) 2009 Elsevier Ltd. All rights reserved.

  纳米孔金催化剂在胺共存的甲醇中选择性甲醇有氧氧化：甲酰胺的高效合成

  摘要：

  多孔金：使用可重用的纳米金（AuNPore）催化剂（由Au-Ag合金制成），可在烷基胺上进行甲醇的高度选择性好氧氧化（见图）。这种出色的化学选择性使甲醇和胺混合物中的烷基胺直接进行N-甲酰化反应。显着的催化活性归因于金与残留在AuNPore中的残留银之间的协同作用。

  Gd14AuxAl86–x Tsai-type 1/1 quasicrystal approximants (ACs) exhibit three magnetic orders that can be finely tuned by the valence electron concentration (e/a ratio). This parameter has been considered to be crucial for controlling the long-range magnetic order in quasicrystals (QCs) and ACs. However, the nonlinear trend of the lattice parameter as a function of Au concentration suggests that Gd14AuxAl86–x

  Gd 14 Au x Al 86– x Tsai 型 1/1 准晶近似体 (AC) 表现出三种磁序，可以通过价电子浓度（ e / a比）进行微调。该参数被认为对于控制准晶体 (QC) 和 AC 中的长程磁序至关重要。然而，晶格参数作为 Au 浓度函数的非线性趋势表明 Gd 14 Au x Al 86– x 1/1 AC 不遵循传统的固溶行为。我们通过单晶 X 射线衍射研究了x值为 52、53、56、61、66 和 73 的Gd 14 Au x Al 86– x样品。我们的分析表明，随着x的增加，Au/Al 的排序会导致由 Gd 原子构成的二十面体壳发生扭曲，并且在原子间 Gd-Gd 距离中观察到的趋势与不同x值下的磁性变化密切相关。我们的结果表明，对于研究 1/1 AC 和 QC 中的长程磁序，单独的 e/a 比可能是一个过于简单化的概念，并且非磁性元素 Au 和 Al 的混合行为在影响磁性方面发挥着重要作用。

  The lattice parameters and macroscopic densities of the solid solutions of Co(Al), Rh(Al), Ir(Al), Ni(Al), Cu(Al), Ag(Al) and Au(Al) and the intermetallic compounds of Ni3AI and Ag2Al were measured over the whole range of homogeneity. The dependence of both the average atomic volume and the enthalpy of formation on mole fraction was investigated for the systems A9-Al (A9 = Co, Rh, Ir), A1O-Al (A10 = Ni, Pd, Pt) and B11-Al (B11 = Cu, Ag, Au). The partial atomic volume and the partial molar enthalpy of aluminium were analysed for phases with the Cu and CU3Au structures. Among the quasi-homological systems, the smallest values for the partial atomic volume of aluminium and the most negative values for the partial molar enthalpy of aluminium were found in the solid solutions A10' (Al). These indicate a strong charge transfer from aluminium-atoms to atoms of nickel, palladium and platinum.

  The Maximum Entropy Method (MEM) has been used to deconvolute the valence-band XPS spectra of thin film Au-Al alloys. The enhanced resolution allows fine changes in the electronic structures of the thin film alloys to be distinguished with the aid of the Au4f core-level spectra. This particular alloy series allows one to examine the 5d electronic interaction between gold atoms as aluminum is gradually added to the matrix. Aluminum is shown to have a much stronger quenching effect on such interactions than has been found previously for copper. (C) 2001 Elsevier Science B.V. All rights reserved.
