为了获得具有应用前景的储氢材料，采用球磨法制备了摩尔比为1：2的Li3AlH6/LiNH2复合材料，并对其储氢性能进行了研究。用X射线衍射仪和傅立叶变换红外光谱对放氢/吸氢后复合材料的微观结构进行了表征。结果表明，球磨过程中有0.65wt%的H_2析出，球磨后的复合材料从室温加热到450℃时有5.97%的H_2脱附，总放氢量达到6.62%。通过对脱氢过程的质谱分析，未检测到NH3。Li3AlH6/2LiNH2复合材料的放氢过程按如下反应进行：Li3AlH6+2LiNH2→Li3AlIn2+2LiH+4H2。在400℃和110bar的氢气压力下，3.57wt%的H_2可以被再吸收。
To obtain promising materials for hydrogen storage, a composite of Li3AlH6and LiNH2with molar ratio of 1:2 was prepared by ball-milling, and its hydrogen storage properties were investigated. The microstructures of the composite after hydrogen desorption/absorption were characterized by XRD and FTIR analysis. The results show that 0.65wt% H2was released during ball-milling process and 5.97wt% H2was desorbed when the post-milled composite was heated from room temperature to 450°C. The total hydrogen desorption capacity reached 6.62wt%. And no NH3is detected by the mass spectrum (MS) analysis over dehydrogenation process. The hydrogen desorption process of Li3AlH6/2LiNH2composite occurs according to the following reaction: Li3AlH6+2LiNH2→Li3AIN2+2LiH+4H2. Furthermore, 3.57wt% H2can be reabsorbed at 400°C and under hydrogen pressure of 110bar.
