    Fabrication of nanoporous palladium by dealloying and its thermal coarsening
    摘要:
    Nanoporous Pd with an average ligament size of 5-20 nm was fabricated by dealloying Pd0.2Co0.8 alloy. An electrochemical potential of +0.5V (vs saturated calomel electrode) on the initial alloy led to Co dissolution in H2SO4 aqueous solution. However, unlike nanoporous Au fabrication from Au-Ag alloy, the free corrosion of Pd0.2Co0.8 alloy in H2SO4 did not result in a nanoporous structure; the electrochemical potential must have been applied to generate a nanoporous structure from the Pd-Co alloy. Thermal coarsening of nanoporous Pd is also investigated. Heating nanoporous Pd increased the ligament size up to 650 nm. it is suggested that a solid state process like recrystallization, rather than melting, is responsible for the thermal coarsening of nanoporous Pd.

    Bimetallic Co–Pd alloy nanoparticles as magnetically recoverable catalysts for the aerobic oxidation of alcohols in water
    摘要:
    Co-Pd bimetallic alloy nanoparticle catalysts were prepared from CoCl2, Pd(OAc)(2) and several capping agents with Li(C2H5)(3)BH. The nanoparticle catalysts were applied to the aerobic oxidation of a variety of alcohols in water to give the corresponding carbonyl products. The catalyst was magnetically recovered and reused for further oxidation. The nanoparticle catalysts were characterized with TEM, ICP, and XPS analyses. (C) 2014 Elsevier Ltd. All rights reserved.

    In order to achieve these goals, we demonstrate a single synthetic protocol to obtain uniform palladium-based bimetallic nanocrystals (PdM, M = V, Mn, Fe, Co, Ni, Zn, Sn, and potentially extendable to other metal combinations) with a wide variety of compositions and sizes based on high-temperature thermal decomposition of readily available precursors. Once the nanocrystals are supported onto oxide materials
    促进剂通过提高速率、稳定性和/或选择性来增强催化活性相的性能。在大多数情况下,识别促进剂的过程是经验性的,并且依赖于测试广泛的催化剂,这些催化剂是用活性和促进剂相的随机沉积制备的,通常没有对其定位进行精细控制。这个问题在支持双金属系统中尤为重要,其中两种金属共沉积到高表面积材料上。我们在这里报告了使用胶体双金属纳米晶体来生产催化剂,其中活性相和促进剂相在一定程度上共定位。该策略使系统方法能够研究几种过渡金属对用于甲烷氧化的钯催化剂的促进作用。为了实现这些目标,我们展示了一种单一的合成方案,以获得具有多种成分和尺寸的均匀钯基双金属纳米晶体(PdM、M = V、Mn、Fe、Co、Ni、Zn、Sn,并可能扩展到其他金属组合)关于容易获得的前体的高温热分解。一旦纳米晶体被负载到氧化物材料上,空气中的热处理会导致靠近 Pd 相的贱金属氧化物相发生偏析。我们证明,与单金属 Pd 催化剂相比,某些金属(Fe、Co

    Abstract In this study, the magnetic susceptibility of the Pd–Co–H system was simultaneously measured with pressure–composition isotherms at ambient temperature. The magnetic susceptibility of the system abruptly decreased as the hydrogen content increased to 0.02 for all Pd–Co alloys under study. In the plateau region, the susceptibility decreased linearly with an increase in hydrogen uptake. The
    摘要 在这项研究中,Pd-Co-H 系统的磁化率与环境温度下的压力-成分等温线同时测量。对于所研究的所有 Pd-Co 合金,随着氢含量增加到 0.02,系统的磁化率突然降低。在高原地区,随着吸氢量的增加,磁化率呈线性下降。单金属氢化物相表现出弱磁化率。这些行为根据 Pd-Co-H 系统的电子结构进行了定性解释。随着氢吸收的增加,费米能级上方的 Co 未占据的下旋带逐渐减小;因此,未补偿自旋产生的磁矩减小,铁磁转变温度降低。

    摘要 采用硼氢化物辅助化学还原法成功合成了不同原子比的钯钴合金。钯钴合金的特征在于研究其物理和化学性质。此外,使用4-硝基苯酚(4-NP)的还原,研究了合成合金的催化行为以及钴中合金中钴的加入对催化行为的影响。硼氢化钠将4-NP还原为4-氨基苯酚是研究催化行为的重要模型反应之一,因为它能够根据从实时光谱监测水溶液中计算出的动力学参数评估催化剂。Pd-Co合金对4-NP还原具有良好的催化活性,并计算了它们的速率常数。催化研究表明,制备的Pd-Co合金催化的还原反应遵循拟一级动力学。其中,Pd26 Co 74以最少的7分钟的时间常数6.65 ms -1催化还原反应。计算出相应合金的翻转频率(TOF),发现为26 h -1。 图形概要
