The physicochemical state of a catalyst is a key factor in determining both activity and
selectivity; however these materials are often not structurally or compositionally …

Using coherent X-ray diffraction imaging (CXDI) as an in situ tool, we determined the shape
and strain state of a platinum nanoparticle with≈ 160 nm diameter supported by a strontium …

Atom probe tomography (APT) has been used to characterize commercially prepared Pt,
Pt/Co alloy, and Ir@ Pt core–shell nanoparticles supported on high-surface-area carbon …

The imaging of catalysts and other functional materials under reaction conditions has
advanced significantly in recent years. The combination of the computed tomography (CT) …

An element-selective study of the occupied and unoccupied density of electronic states in Pt
nanoparticles was performed using hard X-ray resonant inelastic X-ray scattering (RIXS). An …

Heterogeneous catalysts often consist of an active metal (oxide) in close contact with a
support material and various promoter elements. Although macroscopic properties, such as …

When studying catalyst materials by in situ chemical microspectroscopy, a trade-off is found
between the spatial resolution and chemical information of the acquired images …

The new generation of energy-dispersive X-ray (EDX) detectors with higher count rates than
