摘要
In this paper, the hydrolysis properties for hydrogen generation by Mg-metal chlorides composites in pure water are investigated. The composites were prepared by high energy ball milling. It is found that the Mg-metal chlorides composites are very promising for hydrogen generation by hydrolysis reaction. The micro-galvanic cell formed by Mg and the other metal which produced by replacement reaction occurred during the ball-milling process is very effective for improving the hydrolysis reactivity. Based on the investigations of different kinds of chlorides additives, it is found that the Mg-10聽wt%FeCl3 composite ball-milled for 30聽min has the best hydrolysis properties with an initial hydrogen generation rate of 1479.1聽ml*g鈭?聽min鈭? and a theoretical hydrogen production yield of 98%in 2聽min.
