In a recent study published in Nature Communications, which was carried out within the context of the SFB/TRR247, the analytical capabilities of ICAN and three-dimensional atomic probe tomography (AST) were used to gain a deeper understanding of the changes in Co2FeO4 and CoFe2O4 nanoparticles during the oxygen evolution reaction (SER).


In the research group of Tong Li at the Ruhr-Universität Bochum, AST investigations were carried out on particles of about 10 nm in size before and after a different number of SER cycles. The three-dimensional atomic distribution showed nanometre-sized composition changes, which were accompanied by a change in activity.


Microfocus X-ray photoemission spectroscopy and transmission electron microscopy analyses, conducted at ICAN, completed the results obtained.
