▎ 摘　　要

NOVELTY - The preparation method of graphene involves adding sodium dodecyl benzene sulfonate to graphene oxide dispersion, stirring, adding strong base to obtained solution, stirring uniformly to obtain a solution, maintaining solution in hydrothermal reaction kettle, washing obtained mixture by filtering and centrifuging. USE - Method is useful for preparing graphene (claimed). ADVANTAGE - The method enables preparation of graphene with non-toxic agents and avoids usage of toxic hydrazine hydrate and other toxic reagents.
