▎ 摘　　要

NOVELTY - Non-carbon heteroatom modified porous graphene framework comprises 0.1-10 wt.% non-carbon heteroatoms where 80-99% of non-carbon heteroatoms are modified at the edges of the graphene sheets and the pores. The framework is assembled by graphene sheet to form three-dimensional structure. A support cavity of 50-5000 nm is present where each graphene sheet has pores of 0.5-5 nm. USE - Non-carbon heteroatom modified porous graphene framework. ADVANTAGE - The product is low-cost and has high-efficiency. The method is simple and safe; has abundant raw materials; and promotes high added value of cheap raw materials, graphene related energy materials production and development of energy industry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of non-carbon heteroatom modified porous graphene framework comprising simultaneously or sequentially adding carbon source and the non-carbon heteroatom source to the water, mixing, adding catalytic graphitization template, mixing to obtain slurry, oven-drying at 80-150 degrees C where molar ratio of carbon atoms and non-carbon atoms in carbon and non-carbon heteroatoms is 5:1-2000:1, drying carbon source, placing non-carbon heteroatom source and catalytic graphitization template in inert gas, calcining, purifying to remove template, filtering, washing and drying.
