3D atomic-scale imaging of mixed Co-Fe spinel oxide nanoparticles during oxygen evolution reaction
Open accessAbstract
The three-dimensional (3D) distribution of individual atoms on the surface of catalyst nanoparticles plays a vital role in their activity and stability. Optimising the performance of electrocatalysts requires atomic-scale information, but it is difficult to obtain. Here, we use atom probe tomography to elucidate the 3D structure of 10 nm sized Co 2 FeO 4 and CoFe 2 O 4 nanoparticles during oxygen evolution reaction (OER). We reveal nanoscale spinodal decomposition in pristine Co 2 FeO 4. The interfaces of Co-rich and Fe-rich nanodomains of Co 2 FeO 4 become trapping sites for hydroxyl groups, contributing to a higher OER activity compared to that of CoFe 2 O 4. However, the activity of Co 2 FeO 4 drops considerably due to concurrent irreversible transformation towards Co IV O 2 and pronounced Fe dissolution. In contrast, there is negligible elemental redistribution for CoFe 2 O 4 after OER, except for surface structural transformation towards (Fe III, Co III)2 O 3. Overall, our study provides a unique 3D compositional distribution of mixed Co-Fe spinel oxides, which gives atomic-scale insights into active sites and the deactivation of electrocatalysts during OER.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
