title: Production of high quality single- or few-layered graphene by solid exfoliation of graphite in the presence of ammonia borane.
abstract: A solid exfoliation method is developed for the synthesis of single- or few-layered (≤5 layers) graphene by ball milling of graphite with ammonia borane. Nearly quantitative yield in which ca. 25% is single-layered graphene can be obtained. We believe that this highly efficient method will offer a facile approach for the preparation of high quality and large quantity graphene.
