Mg10YNi + 4Cu (in mole ratio) powders at 4 MPa H2 followed by sintering at 400 °C for 20 h under an argon pressure of 0.6 MPa. It is found that the kinetic properties of both the disproportionation reaction of Mg2Cu and its reverse reaction can be enhanced in comparison with those of undoped Mg2Cu. The improvement of hydrogen absorption/desorption kinetics is attributed to the nanocrystalline Mg2Ni and YH2/YH3
摘要 通过在 4 MPa H2 下球磨 Mg10YNi + 4Cu(摩尔比)粉末,然后在 400 °C 和 0.6 MPa
氩气压力下烧结 20 小时,合成了具有纳米结构 Mg2Ni 和 YH2/YH3 的 Mg2Cu 合
金。结果表明,与未掺杂的 Mg2Cu 相比,Mg2Cu 的歧化反应及其逆反应的动力学特性均得到增强。吸氢/解吸动力学的改善归因于嵌入在 Mg2Cu 基体中的纳米晶 Mg2Ni 和 YH2/YH3。
