NaBH4 in Graphene Wrapper: Significantly Enhanced Hydrogen Storage Capacity and Regenerability through Nanoencapsulation

A new high-capacity reversible hydrogen-storage material synthesized by the encapsulation of NaBH4 nanoparticles in graphene is reported. This approach effectively prevents phase agglomeration or separation during successive H-2 discharge/recharge processes and enables rapid H-2 uptake and release in NaBH4 under mild conditions. The strategy advanced here paves a new way for application in energy generation and storage.
