这一贡献报告的新方法，我们已经开发了拆卸的3-D UTL框架到2-D lamenches随后的结构修改，包括pillaring。这可以广泛适用，特别是适用于存在D4 R单元的其它沸石，因此对其它多孔固体也应该具有很大的影响。具体地，通过化学选择性方法，层间空间中D4 R单元的受控水解提供具有UTL结构的单个双金属层。对层的进一步操作提供了一种全新的方法（3D到2D到柱撑），为制备具有不同化学和结构性质的改性沸石提供了前所未有的机会。
This contribution reports new methodology we have developed for the disassembly of 3-D UTL framework into 2-D lamellae followed by structure modification including pillaring. This may be widely applicable, particularly to other zeolites that have D4R units present, and so should have great impact also on other porous solids. Specifically, controlled hydrolysis of D4R units in the interlayer space provides individual ultrathin layers with UTL structure by a chemically selective method. Further manipulation of the layers gives a completely novel approach (3D to 2D to pillared) offering hitherto unprecedented opportunities for the preparation of modified zeolites with diverse chemical and structural properties.
