1. 毕业设计（论文）的内容和要求

通过氢化燃烧合成和高能机械球磨制备的Mg95Ni5活性高、容量高、低温储氢性能优异：373 K，100 s内，首次吸氢量达到6.44 wt%。但是完全放氢仍需523 K以上，373 K吸氢只能维持几个循环。其原因吸放氢热效应导致纳米颗粒再结晶长大，高活性产物易被氧毒化失活。本课题对上述样品进行聚合物离心包覆处理，研究离心工艺的改变对于聚合物限域镁基结构的影响，探索最佳的离心工艺及研究该样品的储氢性能并分析其内在联系。

此外，本论文的要求：翻译3000字左右的英文文献一篇。广泛查阅国内外相关文献，撰写文献综述和开题报告。在实验的基础上，整理和分析数据，系统研究不同工艺对限域结构储氢作用机理进行深层次的分析，做出合理解释。撰写论文。
