Abstract

original image

Have a look inside: A magnetic resonance imaging (MRI) procedure allows the distribution of paramagnetic metal-ion complexes inside catalyst bodies to be probed in a quantitative manner, without influencing the sample during measurements (see picture; blue: high 1H NMR signal (low Co2+ concentration) red: low 1H NMR signal (high Co2+ concentration)).
