▎ 摘　　要

NOVELTY - Porous graphene production involves mixing and pre-treating raw materials coal pitch and ammonium salts in a mass ratio of 1:5-20 to prepare a mixed powder. The prepared powder mixed powder at 180-200 degrees C for carrying out oxidation for 12-24 hours. The prepared powder is placed in a porcelain boat in a tube furnace at 300-500 degrees C in an inert atmosphere for 1-2 hours. The obtained product is washed, soaked, and dried to obtain the porous graphene material. USE - Method for producing porous graphene (claimed). ADVANTAGE - The method produces the porous graphene in a simple and cost-effective manner with high specific surface area and uniform pore size distribution, and wide application in the fields of catalysis, adsorption and supercapacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic transmission electron microscopic image of the porous graphene.
