▎ 摘  要

NOVELTY - Preparing porous graphene involves mixing carbon precursor, aluminum-containing compound and solvent in weight ratio of 100:1-100:100, and then stirring mixture at 25-150 degrees C for 1-5 hours. The mixture is heated in an oven at 40-100 degrees C for 1-12 hours to evaporate solvent. The dried material is heated in a furnace at 1100-2000 degrees C for 0.1-10 hours, and then cooled to room temperature. The obtained product is placed in acid solution, and then stirred for 1-5 hours. The obtained material is washed with deionized water. The washed material is dried in an oven to obtain porous graphene. USE - Method for preparing porous graphene (claimed). ADVANTAGE - The method enables to prepare porous graphene with high purity in a simple and cost-effective manner.
