Research Progress on Constructing b-Axis Oriented MFI Molecular Sieve Membranes Based on Two-Dimensional MFI Nanosheets
摘要: 与其它取向的分子筛膜相比，b轴取向的MFI型分子筛膜具有更短的传输距离以及更低的传质阻力。二维MFI纳米片具有纳米级的厚度和较大的横向尺寸，成为构筑b轴取向MFI分子筛膜的理想材料基元，代表了下一代高性能分离膜的重要发展方向。本文综述了二维MFI纳米片的制备方法、组装策略以及二次生长法对MFI纳米片结构调控与非选择性通道缺陷修复。同时，探讨了该领域在规模化制备应用方面所面临的挑战，并对未来发展前景进行了展望。
Abstract: Compared to other oriented molecular sieve membranes, b-axis oriented MFI molecular sieve membranes exhibit shorter transport distances and lower mass transfer resistance. Two-dimensional MFI nanosheets, characterized by nanoscale thickness and large lateral dimensions, serve as ideal building blocks for constructing b-axis-oriented MFI molecular sieve membranes, representing a key development direction for next-generation high-performance separation membranes. This review summarizes preparation methods, assembly strategies, and secondary growth techniques for regulating the structure of Two-dimensional MFI nanosheets and repairing grain boundary defects. It also addresses challenges in scaling up production for practical applications and outlines future development prospects.
