  X-ray analysis of phthalocyanines formed in the reaction of AuCu and AuSn alloys with 1,2-dicyanobenzene

  摘要：

  X-ray investigations of the reactions of copper, tin and their alloys with gold, with 1,2-dicyanobenzene at 210-degrees-C have been performed. It was found that under the conditions used, gold does not take part in the reaction with 1,2-dicyanobenzene, but separates from the alloys. Copper and tin phthalocyanines are formed as the main products of the above reactions. The crystal structure of tin phthalocyanine (SnPC) has been determined. SnPc crystallizes in the triclinic system (a = 12.048(3) angstrom, b = 12.630(3) angstrom, c = 8.671(3) angstrom, alpha = 95.85(5)-degrees, beta = 95.10(5)-degrees, gamma = 68.25(5)-degrees), space group P1BAR, Z = 2. The refined structure with anisotropic temperature factors gave R = 0.041. The Sn atom is coordinated by four isoindole N atoms, the average Sn-N distance being 2.267(6) angstrom. The SnPc molecule is not planar. The Sn atom is 1.1286 angstrom out of the plane of the four coordinating N atoms.

  Au 3 Cu中无序的热力学

  摘要：

  摘要 通过使用差示扫描和弛豫量热法的热容测量研究了化学计量的 Au3Cu 的无序焓以及无序的振动和构型熵。除了这些量热方法，密度泛函理论用于计算零 K 时的无序焓。有序反应的时间尺度大于量热实验的时间尺度，导致非平衡热容量数据。然而，在适当的限度内整合这些数据提供了无序焓的平衡值，由此计算热容和无序熵。研究有序和无序样品的低温热容行为能够分离熵的振动和构型部分。Au3Cu的无序焓低于Cu3Au的一半，最大值为1.46 kJ mol-1。650 K 时的无序熵值为 0.58 R，小振动部分为 0.02 R。确定的构型熵达到无序 A3B 合金在 650 K 时 0.562 R 的理想构型熵。 高于 650 K，理想值略超。

  of Au3Cu1 hollow nanostructure was prepared by the reaction of Cu nanoparticles with HAuCl4. Following a course of aging, the biomineral botallackite Cu2(OH)3Cl nanoflowers were developed with the aid of Au3Cu1 hollow nanostructures at room temperature. It was proposed that the hollow nanospheres could serve as active centers for heterogeneous nucleation and mediated a mineralization process. Scanning

  Gold-copper alloy catalysts were prepared by impregnation of TiO2 (anatase) support with mixed chloride precursors and tested in the gas-phase epoxidation of propene. The bimetallic systems contained different Au-Cu molar ratios and a total metal content of 4 wt.%. The corresponding monometallic AU/TiO2 and Cu/TiO2 catalysts were also prepared for comparison. X-ray diffraction, XPS and transmission electron microscopy studies indicated that alloying was achieved. The copper content in the catalyst seemed to have a strong influence on the dispersion and catalytic properties of the metal particles. In particular, the greater the Cu content in the alloy, the smaller the metal particle. These changes also contributed to an increase in activity and selectivity to propene oxide. The sample with a Cu/Au ratio of 3/1 showed the best catalytic behaviour. Moreover, the catalytic activity of the samples can be correlated with the results obtained by TPR. (C) 2007 Elsevier B.V.

  Intermetallic compounds and alloys are traditionally synthesized by heating mixtures of metal powders to high temperatures for long periods of time. A low-temperature solution-based alternative has been developed, and this strategy exploits the enhanced reactivity of nanoparticles and the nanometer diffusion distances afforded by binary nanocomposite precursors. Prereduced metal nanoparticles are combined in known ratios, and they form nanomodulated composites that rapidly transform into intermetallics and alloys upon heating at low temperatures. The approach is general in terms of accessible compositions, structures, and morphologies. Multiple compounds in the same binary system can be readily accessed; e.g., AuCu, AuCu3, Au3Cu, and the AuCu-II superlattice are all accessible in the Au-Cu system. This concept can be extended to other binary systems, including the intermetallics FePt3, CoPt, CuPt, and Cu-3-Pt and the alloys Ag-Pt, Au-Pd, and Ni-Pt. The ternary intermetallic Ag2Pd3S can also be rapidly synthesized at low temperatures from a nanocomposite precursor comprised of Ag2S and Pd nanoparticles. Using this low-temperature solution-based approach, a variety of morphologically diverse nanomaterials are accessible: surface-confined thin films (planar and nonplanar supports), free-standing monoliths, nanomesh materials, inverse opals, and dense gram-scale nanocrystalline powders of intermetallic AuCu. Importantly, the multimetallic materials synthesized using this approach are functional, yielding a room-temperature Fe-Pt ferromagnet, a superconducting sample of Ag2Pd3S (T-C = 1.10 K), and a AuPd4 alloy that selectively catalyzes the formation of H2O2 from H-2 and O-2. Such flexibility in the synthesis and processing of functional intermetallic and alloy materials is unprecedented.
