The present invention provides a molecular sieve with FER structure and a preparation method thereof, comprising: crystallizing a mixture formed from raw materials containing silicon source, aluminum source, alkali source, imidazole structure directing agent and water. The molecular sieve of the invention is a sheet molecular sieve with FER structure, the crystal thickness is 15-90 nm, which is beneficial to the diffusion of molecules, and is not easy to deposit carbon when used as a catalyst; The existing technology can only synthesize the low silicon-aluminum ratio (<25) sheet ZSM-35 molecular sieve limitation, which is beneficial to expand its application range. |
