▎ 摘　　要

NOVELTY - Heteromorphic porous graphene comprises structural units formed by graphene nanosheets, and linearly distributed vermicular nanopores. USE - The heteromorphic porous graphene is useful in supercapacitor electrode material, conductive filler material, biosensing material, or sewage treatment (claimed). ADVANTAGE - The porous graphene has good electrical conductivity, large specific surface area, and high application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation of the heteromorphic porous graphene comprising dispersing graphene oxide, metal carbonyl compounds, and metal sulfide in a solvent, subjecting the obtained mixed dispersion to solvothermal reaction to obtain a precursor, subjecting the precursor to carbothermal reaction in a protective atmosphere, and washing to obtain the heteromorphic porous graphene.
