Abstract

original image

Blick ins Innere: Mithilfe der Magnetresonanzbildgebung (MRI) lässt sich die Verteilung paramagnetischer Metallionenkomplexe in Katalysatorkörpern quantitativ bestimmen, ohne dass die Probe während der Messung beeinflusst wird (siehe Bild; blau: intensives 1H-NMR-Signal (niedrige Co2+-Konzentration) rot: schwaches 1H-NMR-Signal (hohe Co2+-Konzentration)).
