Abstract
Although deposited metal particles play an important role as heterogeneous catalysts, there is only limited fundamental knowledge about the relationship between their structure, their adsorption behaviour and their catalytic activity. In this article, we describe a strategy giving access to suitable model systems which can be studied with most surface spectroscopic and microscopic techniques. These systems are based on thin oxide films as supports, onto which metal particles of controllable size are grown by vapour deposition. As concrete examples, the preparation of Ir, Pd and Rh aggregates as well as their interaction with CO and C2H4will be discussed.
