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

Abstract

Ammonia borane-derived boron nitride nanopolyhedra with a hollow core@mesoporous shell structure displaying a specific surface area of 200.5 m² g⁻¹, a total pore volume of 0.287 cm³ 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.
