Nitrogen and Sulfur Codoped Graphene: Multifunctional Electrode Materials for High‐Performance Li‐Ion Batteries and Oxygen Reduction Reaction

N and S codoping of graphene is realized by a novel approach: covalent functionalization of graphene oxide using 2-aminothiophenol as a source of both N and S followed by thermal treatment. The resulting N- and S-codoped graphene has potential applications in high-performance lithium-ion batteries and as a metal-free catalyst for oxygen reduction reaction.
