▎ 摘　　要

NOVELTY - Preparing graphene 4A type molecular sieve complex material comprises: (i) taking graphite powder as raw material, converting to graphite oxide using hummer legal method, carrying out thermal expansion and reduction, adding sodium borohydride, carrying out reduction to obtain the desired graphene; and (ii) mixing sodium hydroxide, sodium aluminate and sodium metasilicate into solution, adding 0.4 wt.% step (i) resultant graphene, mixing, carrying out crystallization at 100 degrees C for 4 hours, washing to achieve the pH less than 9, filtrating and drying in oven at 40-50 degrees C. USE - The method is useful for preparing graphene 4A type molecular sieve complex material (claimed). DETAILED DESCRIPTION - Preparing graphene 4A type molecular sieve complex material comprises: (i) taking graphite powder as raw material, converting to graphite oxide using hummer legal method, carrying out thermal expansion and reduction, adding 0.125 times the amount of sodium borohydride, carrying out reduction to obtain the desired graphene; and (ii) mixing sodium hydroxide, sodium aluminate and sodium metasilicate into solution, adding 0.4 wt.% step (i) resultant graphene, mixing, carrying out crystallization at 100 degrees C for 4 hours, washing to achieve the pH less than 9, filtrating and drying in oven at 40-50 degrees C.
