▎ 摘　　要

NOVELTY - Preparing porous graphene comprises fully mixing graphene and metal salt, heat-treating mixed materials under an inert atmosphere, and performing acid treatment of the heat-treated product to obtain the porous graphene. USE - The porous graphene is useful in the field of lithium ion batteries, supercapacitors, fuel cells or sensors (claimed), and lithium ion battery conductive agent, super capacitor electrode material, fuel cell catalyst, and gas sensor. ADVANTAGE - The method: is simple process and economical, and can accurately adjust the pore size and pore shape according to actual needs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for porous graphene.
