相关的层状沸石已被认为是在这个角度的文章从合成方法，材料表征和催化的影响，考虑到层状材料的独特的物理化学特性的角度。研究了层状沸石前体通过溶胀、插层、柱化、脱层和/或剥离处理产生新型层状可接近沸石的潜力，显示了层状沸石所表现出的化学、功能和结构的多功能性。最近的方法基于沸石纳米片的组装，其通过使用双结构导向剂充当无机结构单元，锗硅酸盐的选择性改性和层状混合有机-无机铝硅酸盐的直接生成也被认为是获得具有明确定义的功能的层状固体。层状沸石的催化应用也被强调，指出层状框架中存在的活性位点的高可及性和反应性。
Relevant layered zeolites have been considered in this perspective article from the point of view of the synthesis methodologies, materials characterization and catalytic implications, considering the unique physico-chemical characteristics of lamellar materials. The potential of layered zeolitic precursors to generate novel lamellar accessible zeolites through swelling, intercalation, pillarization, delamination and/or exfoliation treatments is studied, showing the chemical, functional and structural versatility exhibited by layered zeolites. Recent approaches based on the assembly of zeolitic nanosheets which act as inorganic structural units through the use of dual structural directing agents, the selective modification of germanosilicates and the direct generation of lamellar hybrid organic-inorganic aluminosilicates are also considered to obtain layered solids with well-defined functionalities. The catalytic applications of the layered zeolites are also highlighted, pointing out the high accessibility and reactivity of active sites present in the lamellar framework.
