  Low-Temperature Solution Synthesis of the Non-Equilibrium Ordered Intermetallic Compounds Au₃Fe, Au₃Co, and Au₃Ni as Nanocrystals

  摘要：

  Alloys and intermetallic compounds of Au with the 3d transition metals Fe, Co, and Ni are nonequilibrium phases that have many useful potential applications as catalytic, magnetic, optic, and multifunctional magneto-optic materials. However, the atomically ordered Au-M (M = Fe, Co, Ni) intermetallics are particularly elusive from a synthetic standpoint. Here we report the low-temperature solution synthesis of the L12 (Cu3Au-type) intermetallic compounds Au3Fe, Au3Co, and Au3Ni using n-butyllithium as a reducing agent. Reaction pathway studies for the Au3Co system indicate that Au nucleates first, followed by Co incorporation to form the intermetallic. The nonequilibrium intermetallic nanocrystals have been characterized by powder XRD, TEM, EDS, selected area electron diffraction, and nanobeam electron diffraction, which collectively confirm the compositions and superlattice structures.

  evolution of the x-ray diffraction peaks, the transient low temperature melting of Au nanoparticles and following alloying with the substrate were demonstrated via in situ synchrotron radiation x-ray diffraction. Upon heating, the broad diffraction peak of nanosized Au particles with the average diameter of 2.5 nm was suppressed at about 200 °C and soon became sharp due to melting and subsequent solidification

  通过监测 x 射线衍射峰的演变，通过原位同步辐射 x 射线衍射证明了 Au 纳米颗粒的瞬态低温熔化和随后与基材的合金化。加热后，平均直径为 2.5 nm 的纳米金颗粒的宽衍射峰在 200 °C 左右被抑制，并且由于熔化和随后的固化而很快变得尖锐。如果在 Ni 薄膜上进行测试，会出现不稳定的金属间化合物 Au3Ni 和结晶 Au，这是 Au 和 Ni 的过冷液体反应的结果。然而，它在 275 °C 及以上分解。
