The electrocatalyticactivities of a wide range of orderedintermetallic phases toward a variety of potential fuels have been studied, and results have been compared to those of a pure polycrystalline platinum (Pt(pc)) electrode. A significant number of the orderedintermetallic phases exhibited enhanced electrocatalyticactivity when compared to that of Pt, in terms of both oxidation onset potential

AbstractThree solidsolutions in the Pd–Bi–Te system were obtained by high-temperature ampoule synthesis from the elements at 700°C. The crystal structures of the solidsolutions were determined using powder diffraction data by the full-profile Rietveld method. The solidsolutions PdTe0.33Bi0.67 (a = 4.19816(8) Å, c = 5.6861(1) Å), PdTe0.5Bi0.5 (a = 4.18888(9) Å, c = 5.6778(1) Å), and PdTe0.67Bi0.33
摘要Pd-Bi-Te体系中的三种固溶体是通过高温安瓿从700°C的元素合成而获得的。固溶体的晶体结构通过全轮廓Rietveld方法使用粉末衍射数据确定。固溶体PdTe 0.33 Bi 0.67(a = 4.19816(8)Å,c = 5.6861(1)Å),PdTe 0.5 Bi 0.5(a = 4.18888(9)Å,c = 5.6778(1)Å)和PdTe 0.67 Bi 0.33(a = 4.17796(8)Å,c = 5.6733(1)Å)属于PdTe 1 – x Bi x系列:化合物的结构基于Bi原子对PdTe结构(NiAs型,六方晶系,空间群P 6 3 / mmc)中Te原子的统计取代。PdTe 1 – x Bi x系列固溶体中取代的浓度极限在0.67 < x <0.8范围内。能带结构计算证明了所有化合物的金属性质以及PdTe,PdTe 1 – x Bi x和PdBi的类似电子结构。

Unit cell parameters were measured for the solid solutions Pd(Sb), Pd(Bi) and Pt(Sb) in the whole range of homogeneity. The composition dependence of the average atomic volume was investigated for the binary systems Pd-Sb and Pd-Bi. For the solid solutions Pd(Sb) and Pd(Bi), the partial atomic volumes of antimony and bismuth were determined. They are compared with the partial atomic volumes of the 4d (Ag center dot center dot center dot Te) and 5d (Au center dot center dot center dot Pb) elements measured in the palladium-based solid solutions. The increase in the partial atomic volume for the 4d elements Ag and Sb amounts to 16.3%, for the analogous heavy elements An and Bi to 26.1%. (C) 2006 Elsevier B.V. All rights reserved.
