NOVELTY - Purification method for removal of benzene pollutants involves passing graphene through pore-enlarging agent such that template compound forms high structure, chemically activating, reducing bulk density, obtaining high specific surface area graphene, combining with air outlet, and forming core material which is a purified coating of high-structure, high-specific surface area graphene. The high structure is three-dimensional structure that matches benzene compound and includes network structure, a branched structure and/or a dendritic structure. USE - Purification method for removal of benzene pollutants. DETAILED DESCRIPTION - Purification method for removal of benzene pollutants involves passing graphene through pore-enlarging agent such that template compound forms high structure, chemically activating, reducing the bulk density, obtaining high specific surface area graphene, combining with an air outlet, and forming a core material which is a purified coating of high-structure, high-specific surface area graphene. The high structure is three-dimensional structure that matches benzene compound and includes network structure, a branched structure and/or a dendritic structure. The specific surface area of graphene is more than 1000 m2/g.
