Graphical Abstract

Carbeniumionen in Zeolithen: Mit 13C-NMR-Spektroskopie wurden erstmals zwei wichtige Carbeniumionen unter Bedingungen der Methanol-zu-Olefin(MTO)-Reaktion über Chabazit-Zeolithen beobachtet. Die entscheidenden Rollen dieser Ionen im MTO-Zyklus wurden mithilfe kombinierter experimenteller und theoretischer Studien aufgezeigt.
