    This work investigated influence of various treatments on activity of Shirasu-based materials for hydrogen evolution from aqueous ammonia borane solution. The compositions and activity of the Shirasu-based materials were significantly influenced on various solution and calcination treatments. The activity of Shirasu-based materials increased with increasing surface aluminum ratio and decreasing silicon oxide crystalline impurity. The sample treated with treated with ammonia following calcination at 723 K included the highest surface aluminum ratio and the lowest silicon oxide crystals impurity and exhibited the highest activity for the hydrogen evolution.
