摘要

为改善金属配位氢化物及金属氮氢化物的储氢性能

采用球磨法制备了LiAlH

/LiNH

复合材料

并运用差示扫描量热法和热重等测试方法对球磨样品的储氢性能进行了表征.实验结果表明

LiAlH

/LiNH

复合材料在球磨过程中体系的放氢量(质量分数)达2.6%以上

加热至400 ℃时体系的总放氢量达到7%.对LiAlH

/LiNH

复合体系的反应机理进行了初步探讨

认为LiAlH

/LiNH

摩尔比对体系放氢性能和反应机理有较大影响.同时还研究了过渡金属Ti对反应体系的催化作用

结果表明催化剂Ti的添加量(摩尔分数)在3%至5%的范围内对体系性能改善作用较好.

Abstract

To further improve hydrogen storage properties of the metal complex hydrides and metal-N-H compounds

LiAlH

/LiNH

composite is prepared by mechanical ball-milling

and their hydrogen storage properties are characterized with differential scanning calorimetry(DSC)

and thermogravimetry(TG). The results show that more than 2.6% of hydrogen is released for the LiAlH

/LiNH

composite during ball milling; the total hydrogen desorption capacity reaches 7% after heating to 400 ℃. In addition

the reaction mechanism of LiAlH

/LiNH

composite and the catalytic effect of transition metal Ti on the hydrogen storage prope

rties are investigated. It is found that the molar ratio of LiAlH

/LiNH

composite plays a significant role on the reaction mechanism and transition metal Ti exhibits a positive effect on the properties of the composite when the Ti content gets between 3% and 5%.
