The synthesis of hierarchically porous materials usually requires complex experimental
procedures, often based around extensive trial and error approaches. One common …

Two in situnanoreactors' for high-resolution imaging of catalysts have been designed and
applied at the hard X-ray nanoprobe endstation at beamline P06 of the PETRA III …

The hierarchical pore systems of Pt/Al2O3 exhaust gas aftertreatment catalysts were
analyzed with a collection of correlative imaging techniques to monitor changes induced by …

The 3D chemical structure (4D spectromicroscopy) of nanoporous Al2O3 aerogels coated
with ZnO by atomic layer deposition (ALD) was studied by multienergy scanning …

Tomographic imaging of catalysts allows non‐invasive investigation of structural features
and chemical properties by combining large fields of view, high spatial resolution, and the …

A new closed cell is presented for in situ X-ray ptychography which allows studies under gas

Functional porous materials are of increasing importance in energy conversion and
catalysis. Improved analysis is needed to guide optimization. Four-dimensional (4D) …

The structure and function of solid catalysts are inseparably linked at length scales from nm
to cm and beyond. Hard X‐ray tomography offers unique potential for spatially‐resolved …

The performance of functional materials is either driven or limited by nanoscopic
heterogeneities distributed throughout the material's volume. To better our understanding of …

Porosity in catalyst particles is essential because it enables reactants to reach the active
sites and it enables products to leave the catalyst. The engineering of composite‐particle …
