Operando characterization of working catalysts, requiring per definitionem the simultaneous
measurement of catalytic performance, is crucial to identify the relevant catalyst structure …

The rational design of high-performance catalysts is hindered by the lack of knowledge of
the structures of active sites and the reaction pathways under reaction conditions, which can …

Promoters are important in catalysis, but the atomistic details of their function and particularly
their role in reaction instabilities such as kinetic phase transitions and oscillations are often …

In compartmentalized systems, chemical reactions may proceed in differing ways even in
adjacent compartments. In compartmentalized nanosystems, the reaction behaviour may …

In heterogeneous catalysis research, the reactivity of individual nanofacets of single
particles is typically not resolved. We applied in situ field electron microscopy to the apex of …

Scanning photoelectron microscopy (SPEM) and photoemission electron microscopy
(PEEM) allow local surface analysis and visualising ongoing reactions on a µm-scale. These …

Spatio-temporal nonuniformities in H2 oxidation on individual Rh (hkl) domains of a
polycrystalline Rh foil were studied in the 10–6 mbar pressure range by photoemission …

The catalytic behavior of Rh particles supported by three different materials (Rh, Au, and
ZrO2) in H2 oxidation has been studied in situ by correlative photoemission electron …

Self-sustained oscillations in H2 oxidation on a Rh nanotip mimicking a single catalytic
nanoparticle were studied by in situ field emission microscopy (FEM). The observed spatio …

The kinetic behavior of individual Rh (hkl) nanofacets coupled in a common reaction system
was studied using the apex of a curved rhodium microcrystal (radius of 0.65 μm) as a model …
