  Ru元素在稀土过渡金属间化合物析氢反应中的作用

  摘要：

  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 rapid quenching on the magnetism and magnetocaloric effect of equiatomic rare earth intermetallic compounds RNi (R = Gd, Tb and Ho)

  Magnetocaloric effect (MCE) in RNi (where R = Gd, Tb and Ho) compounds has been studied in their arc-melted and melt-spun forms. The compound GdNi has the orthorhombic CrB-type structure (Space group Cmcm, No. 63) and the compound HoNi has the orthorhombic FeB-type structure (Space group Pnma, No. 62) at room temperature regardless of their synthesis condition. However, arc-melted TbNi orders in a monoclinic structure (Space group P2(1)/m, No. 11) and when it is rapidly quenched to a melt-spun form, it crystallizes in an orthorhombic structure (Space group Pnma, No. 62). The arc-melted GdNi, TbNi and HoNi compounds order ferromagnetically at similar to 69 K, similar to 67 K and similar to 36 K (T-C) respectively. While the melt-spun GdNi shows about 6 K increase in T-C, the ordering temperature of TbNi remains nearly the same in both arc-melted and melt-spun forms. In contrast, a reduction in T-C by about 8 K is observed in melt-spun HoNi, when compared to its arc-melted counterpart. Isothermal magnetic entropy change,Delta S-m, calculated from the field dependent magnetization data indicates an enhanced relative cooling power (RCP) for melt-spun GdNi for field changes of 20 kOe and 50 kOe. A lowered RCP value is observed in melt-spun TbNi and HoNi. These changes could have resulted from the competing shape anisotropy and the granular microstructure induced by the melt-spinning process. Tailoring the MCE of rare earth inter-metallic compounds by suitably controlled synthesis techniques is certainly one of the directions to go forward in the search of giant magnetocaloric materials.

  A TbNi-based deuteride has been prepared by hydriding TbNi at a temperature of 297 K and a deuterium pressure no higher than 0.25 MPa. The structure of TbNiD3.3 differs from that of the parent inter-metallic compound, indicating that deuteration causes structural changes in the metallic sublattice. The deuteride has an orthorhombic structure (CrB type, sp. gr. Cmcm) in which the deuterium atoms occupy three positions, 4c, 8f, and 4b, with [Tb3Ni2], [Tb3Ni], and [Tb4Ni2] nearest neighbor environments, respectively.

  Hydrogen interaction with RNi intermetallic compounds and the influence of hydrogen on magnetic properties of these compounds were investigated. Ternary hydrides GdNiH(3.2), TbNiH(3.4), DyNiH(3.4) and SmNiH(3.7) were prepared by hydrogenation of the initial alloys at room temperature and hydrogen pressure up to 0.1 MPa. Hydrides possess orthorhombic CrB-type structure (S.G. Cmcm). The formation of hydrides results in substantial expansion of the metallic sublattices, weakening of the ferromagnetic interactions and decreasing of the paramagnetic Curie temperatures.
