▎ 摘　　要

NOVELTY - A two-dimensional microporous graphene has average pore size of 0.1-2 nm, interpore spacing of 0.3-10 nm, and standard deviation of interpore spacing of 5 nm or less. USE - Two-dimensional microporous graphene used for energy storage materials e.g. electrode active materials, electronic materials e.g. quantum dots, membranes or films e.g. separator and chemical detector, and catalyst. ADVANTAGE - The graphene is capable of doping with heteroelements. The preparation method is simple and economical. The two-dimensional microporous graphene has excellent performance of selectively penetrating molecules or ions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the two-dimensional microporous graphene, which involves: (a) depositing carbon on a zeolite mold having two-dimensional pore structure to prepare carbon-zeolite composite, and (b) removing the zeolite from the carbon-zeolite composite with a leaching solution. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the method for preparing two-dimensional microporous graphene.
