许多金属氧化物有效地改变金属铝（Al）粉末的中性氢气生产
water at room temperature.In this study,hydrogen is generated even more rapidly from the reacted
在室温下,水.在这项研究中,氢是更迅速地从反应生成的
solution when the by-product Al(OH)3 (bayerite) is present.The influence of Al(OH)3 on the hydrogen
解决方案时,Al（OH）3副产物（三羟）是目前.Al（OH）3影响氢
generation during the aluminum/water reaction is highly dependent on the surface area and the crystallinity of Al(OH)3.High surface area and poor crystallinity of Al(OH)3 render the system a rapid
铝/水反应生成过程中是高度依赖于表面和Al（OH）3的结晶.高表面积和Al（OH）3的结晶度差,使系统迅速
hydrogen generation rate.The self-catalytic phenomenon can be explained by the formation of AlO(OH)
产氢速率.自催化现象可以用AlO（OH）形成的解释
(boehmite) from the reaction of by-product b-Al(OH)3 and the surface passive oxide layer Al2O3.
（勃姆石）从副产物Al（OH）3的反应和表面钝化氧化物层Al2O3.
Furthermore,by taking advantage of the exothermic heat from the Al/water reaction,hydrogen yield is
此外,利用放热的铝/水反应,氢气产量
able to reach 70% within 30 min in a common aqueous solution (pH < 10) containing fine Al(OH)3.This
能达到70%的30分钟内,在一个共同的水溶液（pH＜10）含Al（OH）3细.这
hydrogen generation technology relies on common,nontoxic,noncorrosive additives and is therefore
制氢技术依赖于共同的,无毒,耐腐蚀的添加剂,因此
a very promising system for creating a use-on-demand hydrogen source.
一个很有前途的创造需求的氢源使用系统.
