▎ 摘　　要

NOVELTY - Producing graphene, comprises: (i) preparing a mixture of solid precursors from/including stearic acid and the catalysts sodium chloride and sodium hydroxide; (ii) pyrolyzing precursor mixtures in vacuum and in the presence of inert gas to precursor graphene; and (iii) purifying graphene precursors to obtain finished graphene. USE - The method is useful for producing graphene, which is used in digital electronics, energy and composites. ADVANTAGE - The method can produce graphene in large quantities, uniform quality, high degree of purification at low cost, using fatty acids as raw materials instead of graphite in conventional methods.
