Porous materials with micropores and mesopores have attracted much attention as materials potentially applied in various fields such as absorbents, catalysts, energy storage, and so on. The kind of materials showed intrinsic properties compared with other types of materials such as fine particles. This chapter reviewed our recent research about hollow silica-alumina composite spheres for the hydrolytic dehydrogenation of ammonia borane. This chapter has mainly discussed about the role of interparticle space in the hollow spheres on their acidic properties and activity for the hydrolytic dehydrogenation of ammonia borane.
