    Double complex salts [M(NH3)5Cl][M′Br4] (M = Rh, Ir, Co, Cr, Ru; M′ = Pt, Pd): Synthesis, x-ray diffraction characterization, and thermal properties
    摘要:
    Double complex salts (DCSs) with [M(NH3)(5)Cl](2+) (M = Rh, Ir, Co, Cr, Ru) cations and [PtBr4](2-) anions were prepared in high yields. The salts were two-phase mixtures of the anhydrous and monohydro DCSs. Anhydrous analogues containing [PdBr4](2-) anions with M = Cr or Ru were synthesized. All the compounds were characterized using a set of physicochemical methods. The crystal structure of chloropentaamminechromium(III) tetrabromopalladate(II) was solved: space group Pnma, Z = 4, a = 17.068(2) angstrom, b = 8.315(12) angstrom, c = 9.653(14) angstrom. The [M(NH3)(5)Cl][M'X-4] (M = Rh, Ir, Co, Cr, Ru; M' = Pd, Pt; X = Cl, Br) compounds were shown to be isostructural. The [M(NH3)(5)Cl][PtBr4] center dot H2O monohydrates are isostructural to the [M(NH3)(5)Cl][PdCl4] center dot H2O monohydrates (space group P2(1)/c, z = 4). The properties of the compounds were comparatively analyzed. The tendencies of the thermal stability of the complexes were elucidated. The thermolysis products of the double complex salts obtained under a helium or hydrogen atmosphere were studied.

    surface areas of these nanoporous Pt-based alloy catalysts are increased by over 68 (Pt–Pd), 69 (Pt–Ru) and 113 (Pt–Ir) fold compared to a polycrystalline Pt electrode. All these synthesized nanoporous electrodes exhibit superb electrocatalytic performance towards electrochemical oxidation of methanol and formic acid. Among the five nanoporous Pt-based electrodes, the Pt–Ir shows the highest peak current
    在目前的工作中,已经通过简便的水热方法在钛基体上直接生长了多种基于Pt的双金属纳米结构材料,包括纳米多孔Pt,Pt-Ru,Pt-Ir,Pt-Pd和Pt-Pb网络。通过扫描电子显微镜,能量色散X射线能谱,X射线光电子能谱,X射线衍射和电化学方法对制成的电极进行表征。与多晶Pt电极相比,这些纳米多孔Pt基合金催化剂的活性表面积增加了68倍以上(Pt–Pd),69(Pt–Ru)和113(Pt–Ir)倍。所有这些合成的纳米孔电极对甲醇和甲酸的电化学氧化均表现出极好的电催化性能。在五个基于Pt的纳米多孔电极中,Pt–Ir在+0处显示出最高的峰值电流密度。50 V,与甲醇氧化的多晶Pt相比,提高68倍,甲酸氧化时提高86倍;而纳米多孔Pt–Pb电极在低电位区域的甲酸氧化催化活性优于其他材料,与+0.15 V的多晶Pt相比,其电流密度提高了280倍。这项研究适用于合成多种双金属和三金属纳米多孔材料,是电

    specific feature of the tubular hydrogen electrode is that it is so small that it can fit in microanalytical or electrochemical cell systems. The tubular hydrogen electrode can also work as both a counter electrode and a nonpolarizable reference electrode because of the very large specific surface area of the platinum particles deposited inside. This makes these tubular hydrogen electrodes usable in two-electrode
    本文介绍了一种新型的微型氢电极,它由管状聚合物电解质组成,适合用作电化学测量中的参比电极。管状氢电极是通过将铂黑粉末负载在全氟化聚合物电解质管内并将氢气送入管中来制造的。它可以用作酸性电解质溶液和测试设备(例如聚合物电解质燃料电池)中电化学测量的参比电极。管状氢电极的特点是它非常小,可以安装在微量分析或电化学电池系统中。由于沉积在内部的铂颗粒的比表面积非常大,管状氢电极还可以用作反电极和不可极化的参考电极。这使得这些管状氢电极可用于双电极电池,这是优于传统玻璃型氢参比电极的另一个优势。

    Arrays of Ru, Pt, and PtRu one dimensional 1D nanowires NWs and nanotubes NTs were prepared by electrodeposition through the porous structure of an anodic aluminum oxide AAO membrane. In each case, micrometer-long NW and NT were formed with an outer diameter of ca. 200 nm, close to the interior diameter of the porous AAO membrane. Arrays of NW and NT can be formed by varying the metallic salt concentration

    further shows that the cosputtered films are highly alloyed. The electrochemical behavior of the sputtered films has been evaluated for methanol oxidation using cyclic voltammetry and chronoamperometry in the H 2 SO 4 /CH 3 OH electrolyte at room temperature. The results indicate that Pt 0.53 Ru 0.47 is the optimal alloy composition for highly concentrated 16.6 M CH 3 OH, which corresponds to the stoichiometric
    对于采用 1:1 化学计量甲醇-水重整混合物的直接甲醇燃料电池 (DMFC) 中可能的催化阳极,我们研究了广泛组成范围内的溅射 Pt-Ru 催化剂。由扫描电子显微镜研究确定的催化剂薄膜的表面形态是粗糙和纳米多孔的,并且取决于组成。通过X射线衍射分析证实薄膜的结构为多晶,这进一步表明共溅射薄膜是高度合金化的。使用循环伏安法和计时电流法在室温下在 H 2 SO 4 /CH 3 OH 电解质中评估了溅射薄膜的电化学行为,用于甲醇氧化。结果表明,Pt 0.53 Ru 0.47 是高浓度 16.6 M CH 3 OH 的最佳合金成分,这对应于将用于旨在减轻甲醇交叉的下一代 DMFC 中的化学计量燃料。长时间计时电流法测量表明,溅射 Pt-Ru 催化剂在初始衰减后保持稳定的性能。

The fluorescence detection method, which is a high-throughput technique developed for large arrays of electrocatalysts, can distinguish active
    燃料电池电催化剂的筛选和测试通常涉及在与其在膜电极组件中的使用不完全匹配的条件下进行比较。我们通过四种不同的技术比较了几种商业和自制 Pt 和 PtRu 催化剂在电化学甲醇氧化中的活性;甲醇/硫酸水溶液中的圆盘电极线性扫描伏安法,含有荧光酸碱指示剂的甲醇水溶液中的光学荧光检测,具有大公共反电极的 25 电极阵列燃料电池中的稳态伏安法,以及稳态伏安法传统的直接甲醇燃料电池。荧光检测方法是一种为大阵列电催化剂开发的高通量技术,可以区分活性催化剂和非活性催化剂,但它没有准确地排列活性催化剂。圆盘电极和阵列燃料电池方法都给出了所研究催化剂的可靠排名。最好的一致性出现在阵列燃料电池和单电极燃料电池催化剂等级之间。发现通过不同方法制备的具有相同标称组成的 PtRu 催化剂具有广泛的催化活性。
