  • Intermetallic Ni<sub>2</sub>Ta Electrocatalyst for the Oxygen Evolution Reaction in Highly Acidic Electrolytes
    作者:Jared S. Mondschein、Kuldeep Kumar、Cameron F. Holder、Kriti Seth、Hojong Kim、Raymond E. Schaak

    oxygen evolution reaction (OER) in highly acidic electrolytes is a critical bottleneck in the development of many water-splitting technologies. Bulk-scale solid-state compounds can be readily produced using high-temperature reactions and therefore used to expand the scope of earth-abundant OER catalysts capable of operating under strongly acidic conditions. Here, we show that high temperature arc melting
    能够催化高酸性电解质中的释放反应(OER)的材料的鉴定是许多分解技术发展中的关键瓶颈。大规模固态化合物可以使用高温反应轻松生产,因此可用于扩展能够在强酸性条件下运行的富含地球的OER催化剂的范围。在这里,我们表明,高温电弧熔化和粉末冶反应可用于合成由属间化合物Ni 2 Ta组成的电极,该电极可在0.50 MH 2 SO 4中催化OER 。电弧熔化的Ni 2 Ta电极以10 mA / cm 2的电流密度释放出氧气腐蚀时间> 66 h,腐蚀速率比纯Ni腐蚀速率低2个数量级。多晶Ni 2 Ta粒料产生10 mA / cm 2的电流密度所需的过电势为570 mV。该策略可以推广到包括其他第一行过渡属,包括属间Fe 2 Ta和Co 2 Ta体系。

  • Cross over between ferro and antiferromagnetic order in Fe itinerant electron magnetism: An experimental and theoretical study of the model (Hf,Ta)Fe 2 Laves phases
    作者:L.V.B. Diop、D. Benea、S. Mankovsky、O. Isnard

    日期:2015.9
    Band structure calculations are reported to describe the effects of Ta for Hf substitution on the electronic structure of the Laves phase of HfFe2. According to experimental results emphasis is put on the investigation of the Hf0.825Ta0.175Fe2 composition in comparison with the reference HfFe2 and TaFe2 compounds. By investigation of the theoretical interatomic exchange interactions constants, we showed the influence of the magnetovolume effect on the magnetic phase stability for one intermediate composition Hf0.825Ta0.175Fe2, chosen in the most interesting part of the magnetic phase diagram with coexistence of ferromagnetic (FM) and antiferromagnetic (AF) behaviour. Evolution of the a lattice parameter is found to drive the change from FM to AF magnetic order. A detailed study of the interatomic Fe-Fe exchange coupling constants and their lattice dependence reveals that the ferromagnetic interaction with the first shell is strongly reduced upon contraction of the a lattice parameter.

  • Fe16Nb6Si7 and Fe16Ta6Si7: New D8a phases synthesized by the crystallization of mechanically alloyed amorphous powders
    作者:Georg Rixecker、Robert Haberkorn
    DOI:10.1016/s0925-8388(00)01293-7
    日期:2001.3
    Ternary phases with the cubic D8(a) structure (isostructural to Mg16Cu6Si7) were identified in both the Fe-Nb-Si and Fe-Ta-Si systems. They form during the crystallization of mechanically alloyed amorphous materials and are thermally stable during heat treatments up to 90 h at 1050 degreesC. The X-ray powder diffraction data were evaluated (i) by local line fit, and (ii) by Rietveld analysis. Mossbauer spectroscopy was used to complement the XRD results and to show the absence of magnetic ordering above 77 K. (C) 2001 Elsevier Science B.V. All rights reserved.
