摘要通过HVDS- П高真空甩带机熔炼制备一种能快速水解制氢的Al- Ni合金，考察了合金成分以及碱溶液浓度对铝水解制氢性能的影响。由水解曲线和XRD结果表明，添加一定量的Ni能有效的提高合金的活性，常温下该系列合金与水反应迅速。在20%浓度的KOH溶液中，反应速率由纯Al的1.53 mL /(min·cm2)增加到Al- 3%Ni合金的2.31 mL /(min·cm2)，同时显著地减少了制氢反应时间，Al- 4%Ni合金能在60 min内反应完全，而纯Al需要140 min，反应时间是Al- 4%Ni合金的2倍。由不同的碱溶液浓度得到的实验结果显示，碱浓度提高能直接加快反应速率。Al- 4%Ni合金由1.99 mL /(min·cm2)（15% KOH）增大到3.0 mL /(min·cm2)（25% KOH）。
Abstract：A novel material for rapid generating hydrogen by splitting water, Al- Ni alloy, was prepared by HVDS- П high vacuum machine. The effects of alloy composition and concentration of alkali solution were studied through the hydrolysis experiments and XRD analysis. The results showed that add a certain amount of Ni can improve the activity of the alloys. The hydrogen production rate increase from 1.53 mL /(min·cm2) (x=0,in 20%KOH) to 2.31 mL / (min·cm2) (x=3, in 20%KOH). The hydrogen reaction time of Al alloy was twice of Al- 4%Ni alloy. The different alkali solution concentration experiments results showed that the alkali concentration can improve directly to speed up the reaction from 1.99 mL / (min·cm2) (x=4, in 15% KOH) to 3.0 mL / (min·cm2) (x=4, in 25% KOH).
