-Metals such as gold or palladium are often used as catalysts to speed up certain chemical reactions. When the atoms ball together, most of them do not get into contact with the surrounding gas any more and the catalytic effect diminishes drastically, but these processes are insufficiently understood. While small clusters are highly efficient catalysts, it is still unknown what happens at the extreme, where isolated metal atoms reside on the surface — it was close to impossible to have single metal atoms on an oxide surface. The Fe<sub>3</sub>O<sub>4</sub>(001) surface allows us to study both, isolated metal adatoms that are stable up to surprisingly high temperature [5], as well as the processes leading to cluster formation and growth of clusters [7].+Metals such as gold or palladium are often used as catalysts to speed up certain chemical reactions.
