The invention discloses a graphene/molecular sieve composite catalyst and a preparation method thereof. The composite catalyst comprises, by weight, 5-40% of graphene and 60-95% of molecular sieve. The composite material has a quasi-two-dimensional lamellar structure, the ratio of the area of a single lamella to the thickness of the single lamella is more than 100 micrometers, the molecular sieve is evenly loaded on the surface of the graphene, and mesopore diameter is 2-30 nanometers. The preparation method includes: mixing the graphene, a silicon source, an aluminum source and a surfactant, separating out a graphene-containing part, crystalizing, purifying, and removing the surfactant. The graphene/molecular sieve composite catalyst has the advantages that the composite catalyst serving as a solid acid catalyst has enhanced catalytic activity, product yield and reusability can be evidently increased while the catalytic activity is not lowered when the catalyst is used in CBG and EHB reaction, and accordingly the catalyst is promising in application prospect.
