The effect of Ni and Al addition on hydrogen generation of Mg3La hydrides via hydrolysis

Abstract: Hydrogen generation by hydrolysis of hydrogenated Mg3LaNi0.1, and Mg3LaNi0.1Al0.1 in pure water at room temperature has been investigated and compared with that of Mg3La. It has been found that hydrolysis reaction rate of those hydrides, which are obtained by induction melting and then hydrogenated, is fast when they are immersed in pure water. The highest hydrogen yield is 1024 ml/g for hydrogenated Mg3LaNi0.1. The kinetics of hydrogen production reaction for hydrogenated Mg3LaNi0.1, and Mg3LaNi0.1Al0.1 hydrides at 298 K was also measured. The effect for addition of Ni and Al was also discussed in this paper. [ABSTRACT FROM AUTHOR]
