  PrNi and CeNi hydrides with extremely high H-density

  摘要：

  The new hydrides, PrNiHx and CeNiHx were synthesized by two different techniques: at low hydrogen pressure (p(H2)) and elevated temperature, and at p(H2) = 60 bar and room temperature. The products of both techniques have similar crystal structure derived from the CrB-type. The volume expansion due to hydrogenation reaches 25% in PrNiH4.3 and 29% in CeNiH4.0. PrNi is an effective hydrogen getter. (c) 2005 Elsevier B.V. All rights reserved.

  Metal Flux Growth of Praseodymium Iron Carbides Featuring FeC₃ Units

  摘要：

  铁和碳在 Pr/Ni 共晶通量中的反应产生了三种新的 Pr/Fe/C 碳金属化合物。Pr14Fe6C13 形成于四方空间群 P42/mnm；Pr26Fe19C29 形成于正方空间群 Pmmn。这两种结构都具有三棱平面的 FeC3 基团，这些基团的角和边共享编织出复杂的网络，将镨阳离子包裹其中。在产生 Pr26Fe19C29 的同一反应中，还观察到一种可能的碳化物氢化物 Pr15(FeC6)4H（P6̅ 空间群）。我们收集了这些材料的磁感应强度数据，它们都表现出复杂的磁性。在高温顺磁状态下，显示出反铁磁耦合力。然而，在低温下，Pr14Fe6C13 和 Pr26Fe19C29 的铁磁相互作用占主导地位，它们的居里温度分别为 ∼33 和 14 K。对于低温下的 Pr15(FeC6)4H，在 20 K 以下会出现铁磁或悬臂反铁磁有序。

  replacing the commercial Pt metal in the hydrogen evolution reaction (HER). In this work, RENi2 and RERu0.25Ni1.75 (RE = Pr, Tb, and Er) were synthesized and their electrocatalytic HER activities were explored. Among undoped compounds, PrNi2 exhibits the best performance and requires an overpotential of 55 mV, while partially replacing Ni with Ru element (PrRu0.25Ni1.75) can greatly reduce the overpotential

  基于过渡金属的金属间化合物是有前途的电催化剂，可用于替代析氢反应 (HER) 中的商业 Pt 金属。在这项工作中，合成了 RENi 2和 RERu 0.25 Ni 1.75 (RE = Pr、Tb 和 Er)，并探索了它们的电催化 HER 活性。在未掺杂的化合物中，PrNi 2表现出最好的性能，需要55 mV的过电位，而用Ru元素部分替代Ni（PrRu 0.25 Ni 1.75）可以在10 mA/cm 2的电流密度下将过电位大大降低至20 mV. 这种增强被认为属于它们的外在特性，并且在将电催化表面积归一化后，它们的内在 HER 活性相似。单片机进一步调查2和SCRU 0.25中号1.75（M = Co和Ni）表明在该SCCO掺杂钌元件2将显著增强周围的费米能级（反键字符Ë ˚F）和削弱氢吸附能。在另一方面，对于SCNi上的反键人口2和SCRU 0.25镍1.75是类似Ë ˚F，占他们的亲密内在她的活动。

• Effect of sintering conditions on the formation of single-phase NdMgNi4 compound and its hydrogen storage properties

  Effects of different sintering conditions on the formation of single-phase NdMgNi4 compound and its electrochemical properties have been investigated. XRD analysis shows that an ideal single-phase compound of NdMgNi4 can be synthesized by sintering the pressed tablets of mixture of Mg, Ni and NdNi powders under 973 K for 5 h; single-phase compounds of REMgNi4 (RE = La, Ce, Pr) can be synthesized in this way as well. The electrochemical properties were measured by simulated battery tests. The maximum discharge capacity of NdMgNi4 compound was about 200 mAh/g, and just 78 mAh/g for CeMgNi4 compound. NdMgNi4 compound could store 3.5 H/M of hydrogen under 2.5 MPa at 298 K, whilst it is difficult to absorb hydrogen at a higher temperature (473 K). (c) 2006 Published by Elsevier B.V.
