▎ 摘　　要

NOVELTY - Preparing nitrogen doped porous graphene comprises (i) mixing graphene or modified graphene with etchant in aqueous solution, drying, placing nitrogenous compound in a closed container and incubating at 50-200 degrees C for 30 minutes, and (ii) placing closing container of step (i) in the microwave for few seconds and performing acid treatment to obtain nitrogen-doped porous graphene. USE - The graphene is useful for supercapacitors or lithium-ion batteries (claimed). ADVANTAGE - The graphene has low cost.
