BN working: Under ambient conditions, ammonia-borane (AB) dehydrogenates to polyborazylene, which, in a recent advance, can be readily regenerated in a key step for hydrogen-storage applications (see scheme). In contrast, recent reports show that dehydrogenation of AB under chemical vapor deposition conditions yields atomically thin films of hexagonal BN and their hybrids with graphene.
