Abstract
The present invention relates to a method for synthesizing graphene/sulfur composite, involving the steps of mixing graphene oxide (GO) with a hydrogen sulfide (H2S)-releasing agent in a sealed vessel, causing the H2S-releasing agent to release hydrogen sulfide, and then allowing the hydrogen sulfide to react with the graphene oxide at an elevated temperature and pressure to form said graphene/sulfur composite.
