  通过硫醇金 (Au(I)) 插入实现金簇的异构体选择性转化

  摘要：

  异构体选择性转化是金团簇合理设计中的一个具有挑战性的目标。在此，我们证明了通过与金反应，Au 18 (S c C 6 ) 14 (S c C 6 = 环己烷硫醇)异构体选择性转化为高产率的Au 24 (SR) x (S c C 6 ) 20– x (I)硫醇盐(AuSR)络合物。电喷雾电离质谱分析表明，Au 18 (SR) x (S c C 6 ) 14– x中插入了偶数个 AuSR 单元通过中间体Au 20 (SR) x (S c C 6 ) 16– x或Au 22 ( SR ) x (S c C 6 ) 18– x生成Au 24 ( SR) x (S c C 6 ) 20– x 。这些结果表明，表面 Au(I)SR 低聚物中的组成原子数量仅增加，而 Au 核心中的电子数量保持不变。UV-vis 分析揭示了两种 Au 24 (SR) x (S c C6 ) Au 18 (S c C 6 )

  Spectral correlation in the adsorption of aliphatic mercaptans on silver and gold surfaces: Raman spectroscopic and computational study

  摘要：

  Spectral shifts of the nu(CS) vibrations of several aliphatic mercaptans adsorbed on the Ag and Au electrode surfaces were measured with the surface-enhanced Raman scattering. influence of the chemisorption mechanism on the spectral shift was investigated through ab initio quantum mechanical calculation for CH3SH, CH3S-, CH3SNa, and CH3SMn (M = Ag, Au and n = 1-3). It was found that even though the 2e molecular orbital of methanethiolate makes the major contribution to its chemisorption, the 3a(1) orbital is mainly responsible for the nu(CS) spectral shift. Adsorption of thiolates on the roughened Ag electrode surface seems to occur at the multiple sites such as the three-fold hollow sites while the number of the surface Au atoms interacting effectively with thiolates seems to be less than that of the Ag atoms.

  The alloying of monometal nanoparticles with a transition element has recently attracted extensive interest; however, the dealloying of alloy nanoparticles has rarely been reported. Two-way alloying and dealloying in metal nanoparticles is not known so far to the best of our knowledge. In this work, for the first time, we successfully achieved two-way alloying and dealloying of cadmium in metalloid gold clusters via an antigalvanic reaction in combination with a quasi-antigalvanic reaction and demonstrated reactant-ion-dependent dealloying as well.
