Abstract:

In recent decades, fabrication of zeolite layers has attracted much research interest due to their potential applications in fields of separation, catalysis, sensing, and anticorrosion. Among them, uniformly oriented zeolite layers which benefit from reduced diffusion path lengths and decreased grain boundary defects have become the focus of researchers’ attention. In this review, major achievements made in oriented zeolite layer preparation were reviewed and commented with particular emphasis on the preparation of two-dimen- sional MFI nanosheets, deposition of b-oriented MFI seed monolayers, and microstructural manipulation of b-oriented MFI layers during secondary growth. Moreover, major problems hindering their bulk production were introduced and possible solutions were proposed. Finally, further development in this research field was highlighted.
