Abstract
Exemplary embodiments provide materials and methods for forming graphene-based exfoliated products with low oxygen contents by a reductive-expansion reaction from a physical mixture containing graphite-based precursor(s) and a chemical agent. Exemplary embodiments also provide materials and methods for forming graphene-based exfoliated products with controllable amounts of nitrogen and/or other impurities incorporated in the material structure as a result of a reductive-expansion reaction from a physical mixture containing graphite-based precursor(s) and a chemical agent.
