利用机械混合法制备了铝汞合金体系.该类合金具有很强的化学活性,在常温下与水反应迅速生成氢气,氢气产量接近理论值.如Al-5%Hg合金水解产生1175 mL/g氢气,氢气产率为99%.考察了添加剂(Zn、NaCl)及球磨时间对铝-汞合金化学活性的影响.结果表明:锌部分取代汞,使铝汞合金的活性降低,且随Al-Hg-Zn合金中锌含量的增加,合金水解产氢气量降低,由1059 mLg(Al-9%Hg-1%Zn)降到427 mL,g(Al-5%Hg-5%Zn);但盐的加入,迅速加快了合金水解速率,从238 mL/(min·g)(Al-10%Hg)增加到457 mL/(min·g)(Al-5%Hg-5%NaCl)].以Al-9%Hg-1%NaCl合金为研究对象,球磨时间由1 h延长到2 h,其Al-9%Hg-1%NaCl合金的水解速率有所提高,但进一步延长球磨时间,反而降低了铝合金的活性,表明球磨时间对铝汞合金的性能有一定的影响.

The milled Al-Hg alloys had high reactivity and quickly reacted with water to produce hydrogen. For example, the Al-5%Hg (mass fraction) alloy finally produced 1 175 mL/g hydrogen with the yield of 99% in pure water at room temperature. Furthermore,effects of the additives (Zn and NaCl) and milling time on the Al-Hg alloys reactivity have been researched. The results showed that the additive Zn reduced the Al-Hg alloy reactivity and the hydrogen yields decreased from 1 059 mL/g (Al-9%Hg-1%Zn) to 427 mL/g(Al-5%Hg-5%Zn) with the additive Zn contents increasing. But the NaCI favored to increasing the hydrogen generation rate from 238 mL/ (min·g) (Al-10% Hg alloy) to 457 mL/ (min-g)(Al-5%Hg-5%NaCl alloy). The hydrogen yield and the hydrogen generation rate of Al-9%Hg-1% NaCl alloy were improved with the milling time increasing from 1 to 2 h, but the properties became worse with longer milling time.
