The creation of intergrown layer-like zeolite crystals is one route to form hierarchical zeolites. Faujasite-type (FAU-type) zeolites are among the industrially most important zeolites and the implementation of hierarchical porosity is a promising way to optimise their catalytic and adsorptive performance. After a short general survey into routes for the preparation of hierarchical pore systems in FAU, we will review the currently existing strategies for the synthesis of FAU with layer-like morphology. Those strategies are mainly based on the presence of morphology modifying agents in the synthesis mixture. However, a very recent approach is the synthesis of layer-like FAU-type zeolite crystals assembled in an intergrown manner in the absence of such additives, just by finely adjusting the crystallization temperature. This additive-free preparation route for layer-like FAU, which appears very attractive from an ecological as well as economic point of view, is highlighted in this review. Concluding, a comparison, including powder X-ray diffraction, scanning and transmission electron microscopy, nitrogen physisorption and elemental analysis, between conventional FAU and three layer-like FAU obtained by different synthesis routes was carried out to show the structural, morphological and textural differences and similarities of these materials.

共生层状沸石晶体的产生是形成分级沸石的一种途径。八面沸石（FAU）型沸石是工业上最重要的沸石，分级孔隙率的实现是优化其催化和吸附性能的一种有前途的方法。在对FAU中分层孔隙系统的制备途径进行了简短的一般调查之后，我们将回顾目前具有层状形态的FAU合成策略。这些策略主要基于合成混合物中形态修饰剂的存在。然而，最近的方法是仅通过精细地调节结晶温度来合成在不存在此类添加剂的情况下以共生方式组装的层状FAU型沸石晶体。这篇综述重点介绍了这种层状FAU的无添加剂制备路线，从生态和经济角度来看，它都非常有吸引力。最后，对常规FAU和通过不同合成路线获得的三层状FAU进行了粉末X射线衍射，扫描和透射电子显微镜，氮物理吸附和元素分析的比较，以显示结构，形态和结构上的差异。和这些材料的相似性。
