Operando X-ray characterization platform to unravel catalyst degradation under accelerated stress testing in CO₂ electrolysis

The authors present a customized operando synchrotron X-ray platform to track simultaneously ion, water and catalyst evolution in CO₂ electrolysis based on membrane-electrode assembly. Enhanced Au durability is caused by a robust crystal structure and strong adhesion to substrate.

Probing atom dynamics of excited Co-Mo-S nanocrystals in 3D

The authors introduce an analytical approach for quantitative analysis of 3D atom dynamics during electron microscopy. They image a Co-Mo-S nanocrystal with 1.5 Å resolution, and observe chemical transformations caused by beam-stimulated vibrations.

Visualizing atomic-scale redox dynamics in vanadium oxide-based catalysts

Redox processes in metal oxide surfaces can exhibit structure sensitivities which are difficult to uncover. Here, the authors use atomic-resolution imaging to demonstrate facet dependent alterations in the surfaces of supported vanadium oxide upon reduction and oxidation.
