  Catalytic effect of in situ formed nano-Mg2Ni and Mg2Cu on the hydrogen storage properties of Mg-Y hydride composites

  摘要：

  Two hydrides nanocomposites, consisting of MgH2-Mg2NiH4-YH2 and MgH2-MgCu2-YH2 phases, were prepared by hydrogenation upon the melt-spun Mg80Y5Ni15 and Mg80Y5Cu15 amorphous alloys, respectively. The catalytic effect of nano-Mg2Ni/Mg2NiH4 and Mg2Cu/MgCu2 particles on hydrogen storage properties of Mg-Y hydride composites have been studied. It is shown that the activated meltspun Mg80Y5Ni15 alloy exhibits higher hydrogen absorption capacity and faster hydriding/dehydriding kinetics than those of the activated melt-spun Mg80Y5Cu15 alloy. The activated melt-spun Mg80Y5Ni15 alloy absorbs about 4.2 wt% hydrogen in 10 min at 200 degrees C, and almost fully desorbs hydrogen within 5 min at 280 degrees C. In contrast, the activated melt-spun Mg80Y5Cu15 alloy absorbs about 4 wt % of hydrogen in 2 h at 280 degrees C, and desorbs 3.7 wt% of hydrogen in 80 min at 300 degrees C. The apparent activation energy of dehydrogenation for the activated melt-spun Mg80Y5Ni15 alloy was calculated to be 83.9 kJ/mol, which is significantly lower than that of 132.3 kJ/mol for the activated melt-spun Mg80Y5Cu15 alloy. The excellent hydrogen storage properties of the activated melt-spun Mg80Y5Ni15 alloy can be attributed to the multiple cracks and refined particle size generated during hydrogenation, and the uniform distributed catalytic Mg2Ni/Mg2NiH4 nanoparticles in the Mg/MgH2 matrix. In contrast, a large amount of Mg2Cu/MgCu2 phase significantly aggregations, and the separation between Mg2Cu/MgCu2 and Mg/MgH2 matrix in the activated melt-spun Mg80Y5Cu15 alloy, which greatly decrease the catalytic effect of Mg2Cu for the activated melt-spun Mg80Y5Cu15 alloy.

  Mn取代对超晶格结构Y-Ni合金晶体结构和循环性能的影响

  摘要：

  本研究研究了 YNi3 的晶体结构、P-C 等温线和循环性质。我们发现氢诱导非晶化 （HIA） 出现在 303 K 的 P-C 等温线的三个循环中，但在 273 K 时未观察到。对 303 K 下的三个循环的分析显示，与第一个循环相比，氢气容量降低了 55%。为了增强加氢性能，用 Mn 代替 Ni。YNi2·7Mn0·3H3.8 的 X 射线 Rietveld 细化表明，氢化物相保留了原始合金的 PuNi3 型结构。a、c、晶胞、MgZn2 型晶胞和 CaCu5 型晶胞的值比原始合金膨胀了 5.6 %、9.3 %、21.9 %、25.0 % 和 18.8 %。结果表明，YNi2·7Mn0.3 在 303 K 下循环 3 次后仍保留了 91% 的初始氢容量。在循环测试中循环 120 次后，YNi3 和 YNi2·7Mn0.3 分别保留了其初始容量的 42% 和 90%。YNi3 在 120 次吸收-解吸循环后的

• Phase transformation relevant to the hydrogenation properties in the YNi3−xCrx
  作者：Huaiwei Zhang、Li Fu

  日期：2019.12

  The phase transitions relevant to the hydrogen storage of the YNi3-xCrx are investigated in the paper. A small amounts of chrome substitutions (x < 1) in the alloys can encourage the YNi3 based phases formation through the Ni-Cr solid solutions or compounds, and the hydrogen storage performances are also improved at this time. There were no other phases in the YCr3 alloys except the Y and Cr. The TPD-DSC analyses of the various hydrides have also been discussed. Ni2Cr compounds can be generated during the alloy heating process, and the reaction enthalpies increased with the chrome contents in the alloys.
