▎ 摘　　要

NOVELTY - Preparation of three-dimensional network graphene with biomass structure involves carbonizing biomass to obtain carbonized biomass material, slicing to obtain sheet-shaped carbonized biomass material, preparing electroplating solution with nickel salt, putting sheet-shaped carbonized biomass material into electroplating solution, electroplating, covering inside of pores in sheet-shaped carbonized biomass material with nickel layer, removing carbonized biomass material to obtain sample composed of nickel oxide, depositing graphene on sample, and removing nickel oxide on which graphene is deposited. USE - Preparation of three-dimensional network graphene with biomass structure. ADVANTAGE - The method provides three-dimensional network graphene with controllable structure and shape.
