The structure–property correlations which direct the formation of specific active-acid sites in nanoporous silicoaluminophosphates (SAPOs) have been explored, to afford a molecular basis for the rational design of solid-acid catalysts. It is demonstrated that the influence of the specific zeotype framework extends beyond modulating Brønsted acidity, with the framework topology playing a fundamental role in reaction kinetics. The structural integrity and nature of the active site has been probed using a combined catalysis and multi-technique characterization study, aimed at optimizing the production of ε-caprolactam.

研究硅铝磷酸盐中框架拓扑和可访问的活性位点对调节酸催化作用的作用†

已经探索了结构-性质的相关性，该结构性性质指导纳米多孔硅铝磷酸盐（SAPOs）中特定活性酸位点的形成，为合理设计固体酸催化剂提供了分子基础。结果表明，特定的构型构架的影响超出了调节布朗斯台德酸度的范围，构架拓扑在反应动力学中起着根本性的作用。活性位点的结构完整性和性质已通过结合催化和多种技术表征研究进行了探索，旨在优化ε-己内酰胺的生产。
