▎ 摘　　要

NOVELTY - Preparation porous graphene involves mixing carbon source with the sheet template agent to obtain carbon source-template complex. The carbon source-template complex is wrapped on the surface of sheet template. The carbon source-template complex is added to silicon carbide carbide product at 500-900 degrees C under protective atmosphere and washed and purified with acid to obtain porous carbon sheet. The porous carbon sheet is calcined at 1000-2000 degrees C under protective gas atmosphere to obtain desired product. USE - Method for preparation porous graphene (claimed). ADVANTAGE - The method enables to prepare porous graphene in cost effective manner that has high yield and uses cheap raw material.
