The invention discloses a kind of graphene/molecular sieve composite catalyst and preparation method thereof, which includes graphene and molecular sieve, the quality proportioning of the two are as follows: graphene: 5% ~ 40%；Molecular sieve: 60% ~ 95%；Gained composite material has quasi- two-dimensional slice structure, and the ratio between area and thickness of monolithic layer are greater than 100 microns, and molecular sieve Load Balanced on the surface of graphene, mesoporous diameter is in 2 ~ 30 nm.The preparation method comprises the following steps: graphene, silicon source, silicon source and surfactant are mixed first, containing graphene part is then demultiplex out, then carry out Crystallizing treatment, is finally purified and removed surfactant.Mesoporous graphene/molecular sieves compound material provided by the present invention has the catalytic activity reinforced as solid acid catalyst, for in CBG, EHB reaction, the yield of product can be significantly improved and reusability and do not reduce catalytic activity, had a good application prospect. |
