  Ni3Ga—an investigation of ordering kinetics by residual resistometry

  摘要：

  Order-disorder transformations in the compound Ni3Ga with L1(2) superstructure were investigated by residual electrical resistometry during isochronal and isothermal step-annealing treatments. Resistivity measurements after several isochronal annealing treatments at rising and failing temperatures in the range at 293-800 K showed a complex annealing behavior of Ni3Ga. The first registration of a slight atomic mobility was identified already at 380 K, followed by the second step in atomic mobility observed between 500 and 650 K and attributed to a change in the degree of Iona range order (LRO) in the structure. Measurements at isothermal annealing have been performed after isothermal step treatments between 673 and 786 K also at rising and falling temperatures. The analysis of electrical resistivity curves allowed for conclusion that the order-disorder equilibrium in Ni3Ga is reached not in a single exponential process, but as a result of two processes with distinctly different rates. The ordering activation energies of both fast and slow processes in Ni3Ga were calculated. For the first, fast relaxation process an activation energy parameter was found equal to 1.47 eV; the second, slow process was characterized by an activation energy of 2.66 eV. (C) 2004 Elsevier B.V.

  Certain alloys of nickel have recently been shown to reduce CO2 to multi-carbon products electrochemically without the need for copper. Here we show that Ni3Ga thin film electrocatalysts on carbon electrodes discriminate between CO2 reduction pathways and products based on their surface morphologies, which are controlled by catalyst-carbon support interactions. It is also observed that unsupported, bulk Ni3Ga reduces CO but not CO2. With this understanding, a tandem electrocatalyst utilizing two variants of the Ni3Ga material-one supported and one unsupported-was developed. In this two-electrode system, CO is generated from CO2 on an electrode optimized for this process, and the CO is then further reduced to methanol in the same reactor. It appears that choice of carbon support impacts the morphology of Ni3Ga during the synthesis of the catalyst, thereby influencing the electrolysis product distribution. (C) The Author(s) 2018.

• Single crystal studies on boron-rich τ-borides Ni23−xMxB6 (M=Zn, Ga, In, Sn, Ir)—The surprising occurrence of B4-tetraheda as a normal case?

  Single crystals of the cubic tau-borides Ni23-xMxB6 (M=Zn, Ga, In, Sn, Ir) were synthesised from the elements at temperatures between 1200 and 1500 degrees C. The structure refinements show that the existence of boron-rich phases is quite common. Starting from the idealised composition Ni20M3'B-6 a part of the metal atoms on site 8c is substituted by B-4 tetrahedra. For M'=Ga a complete exchange seems to be possible leading to the composition Ni20GaB14. For M'=Zn and Sn the formation of solid solutions is less extended. For M'=In no exchange is observed but an unusual pattern of Ni/In distribution is observed. With M=Ir mixed occupations occur for all sites and the boron content varies, too. All compositions were confirmed by EDX measurements. (C) 2010 Elsevier Inc. All rights reserved.
