在微孔硅铝磷酸盐上的甲醇至烯烃（MTO）转化特别适合于将分子水平概念应用于开发定义明确的负载型催化剂。典型的MTO催化剂的活性位点是具有基本有机组分的纳米尺寸的无机笼。改变这种催化剂的选择性的机会包括调整有机组分和通过瓶中合成用额外的无机材料修饰笼。后一种可能性已经通过开发有用和实用的磷酸盐改性催化剂而在实验上实现。
Methanol-to-olefin (MTO) conversion on microporous silico-aluminophosphates is particularly well-suited for the application of molecular-level concepts to the development of well-defined supported catalysts. The active site of a typical MTO catalyst is a nm-size inorganic cage with an essential organic component. Opportunities for altering the selectivity of such catalysts include tailoring the organic component and modification of the cage with additional inorganic material through ship-in-a-bottle synthesis. The latter possibility has already been realized experimentally by the development of a useful and practical phosphate-modified catalyst.
