Abstract
The present study investigated influence of various treatment on activity of Shirasu-based materials for hydrogen evolution from aqueous ammonia borane solution. Various solution treatments and calcination treatment significantly affected on the morphology, compositions, and activity. The sample with high surface aluminum ratio and low silicon oxide crystalline impurity showed high activity for the hydrogen evolution. 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.
