Cover story: STM studies of model catalysts

Using scanning tunneling microscopy (STM) to study model catalyst systems could answer many fundamental questions about catalytic processes. The cover image shows atom resolved STM images of a single-layer MoS2 nanocluster together with a one-to-one structural ball model of the observed nanocluster.

Catalytic activity of Au nanoparticles

Au nanoparticles are catalytically active, unlike bulk Au, which is normally thought of as an inert metal. The size of the nanoparticles goes some way to explaining the origin of this activity.

Mind the gap! Spectroscopy of catalytically active phases
Recent advances enable investigation of catalysts in their active state, but care must be taken to ‘mind the gap’
between investigations under ultrahigh vacuum and those at
ambient pressure.

Using gold nanoparticles for catalysis
Nanoparticulate Au catalysts are active even under mild conditions. This activity makes them suitable for commercial
applications including pollution and emission control.
