Abstract

Methods of pyrolytically producing carbons comprising graphene sheets at temperatures below 800° C. are disclosed. The graphene sheets, which are not substantially stacked, are formed by templating on hexagonal metal oxides, for example. Extensive stacking of the graphene sheets, which would lead to formation of graphite, is avoided at the low temperatures employed. Also provided are methods of producing heavily nitrogen doped graphene comprising carbons. Methods of using graphene and heavily nitrogen doped graphene are also disclosed.
