Ammonia borane (NH_3BH_3) is able to hydrolyze at room temperature to generate hydrogen with high purity. For this feature, ammonia borane is expected as a hydrogen storage material for polymer membrane fuel cells for mobile use. It is reported that nickel-based catalyst is one of the highly active catalysts for this reaction. The morphological effect of nickel based catalyst including composite catalyst on their activity was reported, however, there are few reports to systematically investigate the relation between the morphology and the catalytic activity. In this study, we firstly fabricate the highly active in-situ synthesized hollow nickel-silica spheres and investigate the effects of the preparation condition on their catalytic activity for hydrolytic dehydrogenation of ammonia borane.
