Single Source Precursor-based Solvothermal Synthesis of Heteroatom-doped Graphene and Its Energy Storage and Conversion Applications
Solvothermal processes are considered efficient approaches for the gram-scale production of graphene.
Further modification of graphene by chemical doping is an important approach to tailor its properties. In
this work, we successfully synthesized sulfur-doped graphene by using a solvothermal method with dimethyl
sulfoxide as a precursor, which is a common laboratory reagent. Nitrogen-doped graphene was produced to
demonstrate the generality of this process. These heteroatom-doped graphene materials exhibited high
surface areas and high contents of heteroatoms. Furthermore, the lithium-ion storage properties and oxygen
reduction reaction catalytic activity of these materials were also investigated. The success of this approach
might facilitate the development of other advanced graphene-based materials with relative simplicity,
scalability, and cost effectiveness for use in various potential applications.141421sciescopu
