Synthesis of mufti-functionaIized layered zeoIite by modification of interlayer of zeolitic lamellar precursor and its catalytic application

本研究的目的是通过在沸石片层材料的层间插入不同类型的含金属有机化合物来合成新型结构的沸石，并对沸石进行功能化。通过在层状沸石前体的层间插入不同类型的含硅化合物作为柱试剂，成功地控制了层状沸石材料之一FER型沸石的孔径（层间距离）和亲水性。MWW型沸石是另一种层状沸石材料，通过将含金属化合物（Sn化合物等）插入层间而成功地进行了层间膨胀。MWW型分子筛具有独特的催化性能，基质能够在被层包围的有限空间内反应，生成特定尺寸的产物。

The purpose of this study was the synthesis of novel structured zeolite by inserting various types of metal-containing organic compounds into the interlayer of zeolitic lamellar materials and the functionalization of the zeolites. The pore size (distance between interlayers) and hydrophilicity of FER-type zeolite, which is one of the layered zeolitic materials, was successfully controlled by inserting various types of Si-containing compounds as a pillar regent into the interlayer of the zeolitic lamellar precursor on the basis of the number of atoms. MWW-type zeolite, which is another layered zeolitic material, was successfully interlayer-expanded by inserting metal-containing compounds (Sn-compound etc) into the interlayer. MWW-type zeolite with the novel structure showed specific catalytic properties; substrates were able to react in the confined space surrounded by the layers to turn to products with specific sizes.
