  Al–Pt compounds have been systematically studied as electrocatalysts for the oxygen evolution reaction (OER). Considering the harsh oxidative conditions of the OER, all Al–Pt compounds undergo modifications during electrochemical experiments. However, the degree of changes strongly depends on the composition and crystal structure of a compound. In contrast to Al-rich compounds (Al4Pt and Al21Pt8),

  Al-Pt 化合物作为析氧反应 (OER) 的电催化剂已得到系统研究。考虑到 OER 的严酷氧化条件，所有的 Al-Pt 化合物在电化学实验中都会发生变化。然而，变化的程度在很大程度上取决于化合物的组成和晶体结构。与揭示铝强烈浸出的富铝化合物（Al 4 Pt 和 Al 21 Pt 8）相比，其他化合物（Al 2 Pt、Al 3 Pt 2、rt-AlPt、Al 3 Pt 5和 rt -AlPt 3) 仅发生在地表或近地表区域。此外，表面改性导致 Pt 的电子结构发生变化，从而原位形成催化活性更高的表面，这些表面由金属间化合物、富含 Pt 的 Al x Pt 1- x相和 Pt 氧化物组成。在足够的 OER 活性和稳定性之间形成折衷，Al 2 Pt 和 Al 3 Pt 2可被视为 OER 电催化剂的前体。

  Diffusion data for amorphous binary alloys are scarce in the literature. There are no data available for the diffusion of Al in Al–Pt amorphous phase known to the authors. High-temperature successive deposition of components was used in the present experiments to reveal the elementary processes of reactive diffusion forming the metastable amorphous phase and to determine the diffusion coefficient of

  非晶二元合金的扩散数据在文献中很少见。对于作者已知的 Al-Pt 非晶相中的 Al 扩散，没有可用的数据。本实验采用组分的高温连续沉积来揭示形成亚稳态非晶相的反应扩散的基本过程，并确定该相中Al的扩散系数：D(α)=(1.2±0.4)×10 −10×exp[−(6.9±0.1)×104J mol−1/RT]m2 s−1。这个值取自薄膜实验，可以被认为是体扩散系数的一个很好的近似值。
• AuAl2 and PtAl2 as potential plasmonic materials

  The dielectric functions of PtAl2, AuAl2 and hypothetical intermediate alloys of the two in the form of AuxPt1-xAl2 were calculated from first principles using density functional theory (DFT) and the random phase approximation (RPA). From these, the reflectivity, electron energy-loss spectra (EELS) and small sphere extinction spectra are predicted. The experimental reflectivity and EELS were measured for PtAl2 and showed good agreement with the theoretical spectra. The yellow color of PtAl2 is associated with a bulk plasmon at 3 eV. We predict that the optical properties of hypothetical intermediate alloys would show a smooth evolution with composition. The details of this change can be understood by examination of the underlying density of states (DOS). The predicted small sphere extinction spectra and quality factors show a strong surface plasmon resonance for these materials, with PtAl2 having the optimum performance. The results indicate that these materials are good candidates for applications in plasmonics. (C) 2013 Elsevier B.V. All rights reserved.

  The Al-Ni-Pt phase diagram was studied in the compositional region from 50 to 100 at.% Al. Isothermal sections were determined at 1000, 900 and 790 degrees C. At 1000 degrees C the Al2Pt phase was found to extend up to similar to Al53Ni23Pt24 composition, separating the (Al3Pt2) and (Al3Ni2) phase fields. Two ternary structures were revealed. The one forming between similar to Al75Ni3Pt22 and Al75Ni9Pt16 is rhombohedral isostructural to Al28Ir9 and the other forming between similar to Al73Ni8Pt19 and Al72.5Ni18Pt9.5 has an orthorhombic epsilon(6) structure typical of Al-Pd and Al-Rh.
