Catalytic reactions on platinum metals nanofacets: Spectroscopy on an atomic scale
Otto-von-Guericke-Universitaet Magdeburg, Chemisches Institut, Universitaetsplatz 2, Magdeburg D-39106, Germany
The technical importance of heterogeneous catalysts has motivated an intensive development of model systems emulating the behaviour of dispersed metals on oxidic supports. One of the successful approaches is the creation of arrays of the small metal particles, grown on a planar oxidic support. Most surface-sensitive spectroscopies, however, average the collected data (in the best case over few catalytic pellets of the sample), thus the individual characteristic of the single particles are often "smoothed out". This creates difficulties in addressing the details of the reaction mechanisms on the single metal nanoparticles.
