  Double complex salts [Au(C4H13N3)Cl][MCl6]·nH2O (M = Ir, Pt; n = 0–2) were synthesized. According to X-ray diffraction data, compounds with n = 1.5 are isostructural; the crystal structure is composed of the complex cations [Au(dien)Cl]2+ (dien is diethylenetriamine), the complex anions [MCl6]2−, and water molecules of crystallization. Thermolysis of the double complex salts under hydrogen and helium was studied. The formation of nonequilibrium solid solutions based on Ir in the Au-Ir system and based on Pt in the Au-Pt system was demonstrated.

  A facile method was used to prepare gold-platinum (Au-Pt) catalysts by direct electrodeposition via cyclic voltammetry in an acidic medium. Various parameters that affect the properties of electrodeposited catalysts were investigated such as initial applied potential, scan rate and deposition time. Initial applied potential plays a more important role in the preparation of bimetallic nanoparticles (AuPtNPs) since the kinetics of electrodeposition is in competition with the rate of hydrogen evolution. The AuPtNPs electrodeposited on pencil graphite (PG) were used to study the electrooxidation of hydroquinone. Various parameters such as pH, scan rate, concentration of hydroquinone and temperature were studied in the electrooxidation process. Apparent activation energy (E a) for the electrooxidation of hydroquinone, calculated from the Arrhenius plot, shows that AuPtNPs catalysts (electrodeposited on the PG) offer less activation energy (ca. 9.500 kJ mol−1) than the bare PG (ca. 10.345 kJ mol−1). The AuPtNPs/PG shows better catalytic performance than the PG electrode due to the greater surface area it provides, thus resulting in more active sites available for adsorption of hydroquinone molecules on the surface of the catalyst.

  通过在酸性介质中循环伏安法直接电沉积，采用了一种简便的方法来制备金铂（Au-Pt）催化剂。研究人员研究了影响电沉积催化剂特性的各种参数，如初始施加的电位、扫描速率和沉积时间。在制备双金属纳米粒子（AuPtNPs）时，初始施加的电位起着更重要的作用，因为电沉积的动力学与析氢速率相互竞争。研究人员利用在铅笔石墨（PG）上电沉积的AuPtNPs来研究氢醌的电氧化。在电氧化过程中研究了各种参数，如pH值、扫描速率、氢醌浓度和温度。根据阿列纽斯图计算出的氢醌电氧化的表观活化能（E a）表明，AuPtNPs催化剂（在PG上电沉积）提供的活化能（约9.500 kJ mol-1）低于裸PG（约10.345 kJ

  for reducing PGM usage and enhancing activity, especially as in the case of the Au–PGM bimetallic system. The present work introduces a new way for controllable synthesis of Au-based nanocrystals by the simple addition of PGM anion precursors into an aqueous solution of the citrate/HAuCl4 mixture containing in situ Au nanowires (NWs), at room temperature without the aid of additional reducing agents

  铂族金属（PGM；Pd、Pt、Ir等）具有独特的化学和物理性质，这些性质通常随其尺寸、形态、晶体结构、相和组成而发生巨大变化。然而，由于其成本高、活性不足、稳定性差和资源稀缺，将 PGM 与第二种金属结合生成双金属纳米晶体被认为是减少 PGM 使用和提高活性的有效方法，特别是在 Au- PGM双金属系统。本工作介绍了一种通过将 PGM 阴离子前体简单地添加到原位含有柠檬酸盐/HAuCl 4混合物的水溶液中来可控合成 Au 基纳米晶体的新方法。Au 纳米线 (NW)，在室温下无需额外的还原剂。在此，系统地研究了一系列 PGM 阴离子与原位Au NW 模板的反应过程。这项工作为轻松制造基于 Au 的低 PGM 含量纳米晶体开辟了新的可能性。
