沸石分子筛内引入不同类型的分子、原子、离子后,极大地修饰了沸石的物理化学性质。金属离子和催化活性位的协同作用形成了双功能催化剂。但是由于孔道直径的限制,进入的分子、原子、离子只能作单分散层的一维或二维排列。它不仅为诸如超晶格半导体层结构的形成,离子导电机理和分子存贮,光电转换机理等理论研究提供信息,而且也可能成为这方面的新材料。 Zeolite zeolite into different types of molecules, atoms, ions, greatly modified the physicochemical properties of the zeolite. The synergistic effect of the metal ions and the catalytically active sites forms a bifunctional catalyst. However, due to the limitation of pore diameter, the entering molecules, atoms and ions can only be arranged in one-dimension or two-dimension of monodisperse layer. It is not only for the formation of superlattice semiconductor layer structure, ionic conduction mechanism and molecular storage, photoelectric conversion mechanism theory to provide information, but also may become a new material in this area.
