▎ 摘  要

NOVELTY - Graphene/ZSM-5 molecular sieve composite, comprises 0.04-1.50 wt.% graphene, preferably 0.04-1.0 wt.% and 98.50-99.96 wt.% ZSM-5 molecular sieve, preferably 99.0-99.96 wt.%. USE - The graphene/ZSM-5 molecular sieve composite is useful as catalyst in the reaction of preparing ethylbenzene by benzene/ethylene alkylation. ADVANTAGE - The composite: has high activity, selectivity and intrinsic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a synthetic method of Graphene/ZSM-5 molecular sieve composite, comprising (1) mixing the first silicon source, structure directing agent, graphene and water and heat-treating to obtain the seed crystal, (2) mixing the seed crystal obtained in the resultant step, aluminum source, alkali source, second silicon source and water, then crystallizing and drying, and (3) exchanging the resultant material with ammonium to obtain the final product.
