2011, IntermetallicsCitation Excerpt :Compare, for example, lattice parameter of the Mg3MnNi2 intermetallic compound a = 11.5611 Å and a = 12.1711 Å for isostructural boron-stabilized Mg8Rh4B [19]. If to compare structures of Mg3MnNi2D1.83 and Mg2RhD1.14 with earlier studied hydrides of Ti2Ni-type compounds of titanium and zirconium (or hafnium), one can see that they are closer to those of Ti-containing hydrides, e.g. Ti4Fe2O0.25−1.0D4.9−2.5 [20], in which both tetrahedral and octahedral interstices are occupied, rather than to Zr(Hf)-containing hydrides, Zr3V3OD4.93 [21] and Hf2FeD4.5 [22], in which large octahedral interstices remain empty. As we have observed in this study, the Mg3MnNi2D2.7 deuteride is rather unstable.
Electrocatalytic effects of Mo-Pt intermetallics singly and with ionic activators. Hydrogen production via electrolysis
2007, International Journal of Hydrogen EnergyCitation Excerpt :In spite of the fact that the activity of the electrode is in close correlation with the electronic configuration of individual metals and/or their intermetallics, some of the high electrocatalytic activities could additionally be explained on the basis of the 3D hydride features of composite electrocatalysts. The ability of metals to absorb a certain amount of hydrogen can improve the evolution of hydrogen [20–22]. The main aim of this work is to reduce energy consumption for hydrogen production by using the intermetallics of transition metals as cathode materials in electrolysis singly or in combination with in situ activation by a specific mixture of cobalt and molybdate ions [23].
