    Alloying effects on the hydrogen-storage capability of Pd–TM–H (TM=Cu, Au, Pt, Ir) systems
    摘要:
    Pressure-composition isotherms and the magnetic susceptibilities of Pd-TM-H (TM = Cu, Au, Pt, and Ir) systems were measured at ambient temperature, and the effects of alloying between Pd and transition metals on the hydrogen storage capability of these Pd-TM alloys were investigated by considering their electronic band structures. All of the magnetic susceptibilities for the Pd-TM-H systems decreased linearly with hydrogen uptake. For the Pd-Cu alloy, the magnetic susceptibility was nearly zero at the terminal composition of hydrogen in the plateau region obtained from the pressure-composition isotherm, and the terminal composition decreased with increasing Cu substitution. These results indicated that the hydrogen-storage capability was proportional to the amount of unoccupied d states in the electronic band structure of the Pd-Cu alloy. The Pd-Au-H system exhibited substantially the same behavior as the Pd-Cu-H system. For the Pd-Pt and Pd-Ir alloys, the magnetic susceptibility at the terminal composition of hydrogen in the plateau exhibited a finite positive value, indicating that the unoccupied d states in the Pd-Pt and Pd-Ir alloys were not filled when the maximum quantity of hydrogen was stored in the alloys. These finite magnetic susceptibilities at the terminal composition of hydrogen in the plateau region were explained by the structural modification of the unoccupied d states in the electronic band structures due to alloying.

    聚合物保护的钯-铂双金属簇:制备,催化性能和结构方面的考虑
    摘要:
    在聚(N)存在下,在乙醇-水(1:1,v / v)中回流氯化钯(II)和六氯铂酸(IV)的混合溶液-乙烯基-2-吡咯烷酮)可得到聚合物保护的钯/铂双金属簇的良好分散和稳定的胶体分散体。UV-VIS吸收光谱和透射电子显微照片表明,这些双金属簇粒子的大小均一,每个粒子都包含钯和铂原子。这些双金属簇的分散体被用作催化剂,用于在大气压下在氢气中于30°C下将环辛-1,3-二烯选择性氢化为环辛烯。发现部分氢化的催化活性取决于颗粒的金属组成。对于二烯氢化,具有Pd∶Pt = 4∶1的摩尔比的双金属簇是最具活性的催化剂,其活性是典型的胶体钯催化剂的两倍。

    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.
