Suppression of twins in b-oriented MFI molecular sieve films under microwave irradiation

摘要

Twin growth in the synthesis of b-oriented MFI films is successfully suppressed by applying microwave irradiation on a b-oriented MFI seed layer, relying on the nucleation-related bottleneck effect. Electrochemical oxidation experiments demonstrated the importance of twin suppression in enhancing the diffusion of guest molecules in MFI films.
