The role of structure directing agents in the synthesis of zeolites has been studied through atomistic simulation techniques. Three different kinds of structure directing agents have been reviewed: (i) isomorphic heteroatom Si --> Al and Si --> Ge substitutions; (ii) F(-) anions; and (iii) organic SDAs. The interplay between these structure directing agents is described and the separate effects of each one have been found from energy calculations and analysis of energetic terms.
通过原子模拟技术研究了结构导向剂在沸石合成中的作用。综述了三种不同类型的结构导向剂:(i)同构杂原子Si→Al和Si→Ge取代;(ii)F(-)阴离子;以及(iii)有机结构导向剂。描述了这些结构导向剂之间的相互作用,并通过能量计算和能量项分析发现了每种结构导向剂的单独作用。
