Abstract
A method for manufacturing graphene-based material is disclosed. A graphene oxide dispersion includes graphene oxide dispersed in solvent. A hydrogen sulfide gas is introduced to the graphene oxide dispersion at a reacting temperature to achieve a graphene dispersion. The hydrogen sulfide reduces graphene oxide into graphene, and elemental sulfur produced from the hydrogen sulfide is deposited on surfaces of the graphene. The solvent and elemental sulfur are removed to achieve a graphene composite material.
