Oriented MFI zeolite membranes are membrane materials formed by closely stacking and crosslinking MFI grains or nanosheets in a specific direction. Compared with a-, c-, and (h0h)-oriented zeolite membranes, b-oriented membranes can effectively improve the molecular transmission rate and are widely used in the fields of mixture separation and catalysis. However, twinning can easily occur during the zeolite membrane preparation, and controlling the membrane orientation is difficult owing to the limitations in the crystal growth kinetics. In this review, recent important progress in the preparation strategies and methods of oriented zeolite membranes are introduced, and the microscopic mechanism of the membrane orientation regulation is analyzed, including heterogeneous nucleation and homogeneous nucleation mechanisms. Moreover, the application status of oriented zeolite membranes in the fields of mixture separation and catalysis is summarized. Finally, current challenges and future development perspectives of oriented MFI zeolite membranes are addressed.

定向的MFI沸石膜是通过在特定方向上紧密堆叠和交联MFI颗粒或纳米片而形成的膜材料。与a-，c-和（h0h取向的沸石膜，b取向的膜可以有效地提高分子的传输速率，并广泛用于混合物的分离和催化领域。但是，在沸石膜的制备过程中容易发生孪晶，并且由于晶体生长动力学的限制，难以控制膜的取向。本文综述了定向沸石膜制备策略和方法的最新进展，分析了膜取向调控的微观机理，包括异相成核和均相成核机理。总结了定向沸石膜在混合物分离和催化领域的应用现状。最后，
