Analytical methods that provide direct real-space information about the dynamics of
catalysed reactions often require simplified model systems and operate under high-vacuum …

Atom probe tomography is a well-established analytical instrument for imaging the 3D
structure and composition of materials with high mass resolution, sub-nanometer spatial …

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 …

Catalysis is a highly complex phenomenon involving fundamental processes on multiple
length scales. The full-scale complexity of catalysis is only poorly understood, and how …

We report a unique in situ instrument development effort dedicated to studying gas/solid
interactions relevant to heterogeneous catalysis and early stages of oxidation of materials …

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 interaction of oxygen with a reactive metal is ubiquitous, yet the precise atomic-level
mechanisms and pathways leading to the formation of a surface oxide are not well …

To make available atomic oxygen at the surface of a catalyst is the key step for oxidation
reactions on Au-based catalysts. In this context, Au-Ag alloys catalysts exhibit promising …

Automotive pollution control crucially relies on the reactivity of metal alloy catalysts.
Understanding how the chemistry of an alloy compares with that of pure metals forms a …

Since the early discovery of the catalytic activity of gold at low temperature, there has been a
growing interest in Au and Au-based catalysis for a new class of applications. The …
