▎ 摘　　要

NOVELTY - Preparing graphene comprises mixing strong base solid oxidized graphite alkene solution, mixing uniformly to obtain suspension liquid, removing the water in the suspension and evaporating to obtain solid crystallized salt, crushing the solid, calcining to obtain high specific surface graphene primary product, and drying to obtain the high-specific surface area graphite. USE - Method for preparing graphene (claimed). ADVANTAGE - The method can prepare graphene having high specific surface, is simple, increases safety of the operation, and avoids harm to the operator.
