▎ 摘　　要

NOVELTY - Graphene is produced by successively performing step (a) of reacting catalyst with source carbon solids, step (b) of creating graphene precursor from reaction of catalyst with source carbon solids, step (c) of pyrolyzing graphene precursor, step (d) of extracting graphene from pyrolyzed graphene precursor to obtain extracted graphene, step (e) of washing extracted graphene in hydrochloric acid and filtering to obtain clean and filtered graphene, and step (f) of sonicating clean and filtered graphene with acetone to obtain graphene dispersion. USE - Production of graphene. ADVANTAGE - The method is economical and environmentally friendly, and can produce high quality graphene in large quantities at low cost in commercial production.
