The present application provides a method for synthesizing a FER/MOR composite molecular sieve. The method comprises mixing FER seed crystal, MOR seed crystal, germanium source, aluminum source, water, and acid or alkali to obtain a reaction mixture; and obtaining a crystal by adjusting reaction conditions such as ratio of seed crystal, ratio of bismuth to aluminum and system pH. Compared to an adjustable two-phase composite molecular sieve. The method described in the present application does not need to add any organic template agent during the synthesis process, can reduce the reaction cost, reduce the possible environmental pollution, and has a good application prospect. |
