Two-dimensional zeolites are a relatively new branch of material science attracting still growing attention. They are formed as crystalline nanosheets in various spatial arrangements. We can perceive the zeolite layers as new building blocks for the fabrication of hierarchically porous materials. Unlike their bulk three-dimensional counterparts 2D zeolites excel in facile molecular transport while keeping the strong intrinsic acidity of the zeolite framework. Moreover, due to their large external surface areas they can be employed for bulky molecule reactions. In the presented chapter we discuss 2D zeolites from their early days up to the most recent state-of-the-art methods. Special attention is paid to the progress in structure-directing-agent design, which led to the discovery of directly synthesized hierarchical 2D zeolites.
