Hollow core@mesoporous shell boron nitride nanopolyhedron-confined ammonia borane: a pure B-N-H composite for chemical hydrogen storage

Ammonia borane-derived boron nitride nanopolyhedra with a hollow core@mesoporous shell structure displaying a specific surface area of 200.5 m(2) g(-1), a total pore volume of 0.287 cm(3) g(-1) and a bimodal pore size distribution were successfully prepared and used as nanoscaffolds to improve the dehydrogenation properties of ammonia borane by an exclusive nanoconfinement effect.
