▎ 摘　　要

NOVELTY - Preparing a porous graphene membrane comprises (i) mixing the template agent, carbon precursor and solvent uniformly to prepare a precursor mixture, (ii) forming the mixture film layer on the substrate, (iii) removing the solvent in the mixture to form embryonic membrane, (iv) catalyzing the carbon in the carbon precursor to grapheme and (v) removing the template. USE - The porous graphene membrane is useful in electrode materials and/or water treatment (claimed). ADVANTAGE - The method: is simple, economical and environmentally friendly; and the obtained product has excellent conductivity, three-dimensional porous network structure and excellent market prospect.
