▎ 摘　　要

NOVELTY - Preparation of graphene/carbon nanotube composite comprises taking graphite powder and catalyst precursor to form intercalated graphite and placing in environment suitable for growth of carbon nanotubes. The catalyst precursor is graphite layer forming into graphite intercalation, can be inserted in close environment at high temperature, and can be used to promote decomposition of catalyst material of carbon nanotubes grown in suitable environment. USE - Method for preparing graphene/carbon nanotube composite (claimed).
