Abstract

Innenaufnahme: Die Kombination aus den beiden im Titel genannten Verfahren während der katalytischen Umsetzung von Thiophenderivaten an Zeolithkristallen ergibt räumlich und zeitlich aufgelöste chemische Informationen auch ohne Markierungen (siehe Bild). Das reagierende Thiophen befindet sich hauptsächlich im Kristallinneren, während das Produkt in den geraden Poren des Zeoliths gefunden wird.
