Inverse oxide/metal catalysts have shown to be excellent systems for studying the role of the oxide and the oxide-metal interface in a catalytic reaction. In recent studies, it has become clear that these systems can have especial catalytic properties due to strong oxide metal interactions difficult to obtain when depositing a metal on a regular oxide support. As a consequence of these strong interactions, oxide phases which are not seen or are metastable in a bulk oxide become stable in an oxide/metal system opening the possibility for new chemical properties.Using these systems it has been possible to explore in detail correlations between the structural, electronic and catalytic properties of oxide-metal interfaces and obtain a fundamental understanding of factors which determine catalytic performance in reactions such as the oxidation of CO, the water-gas shif,t and the hydrogenation of CO<sub>2</sub> to methanol.Recently, there has been a significant advance in the preparation of oxide/metal catalysts for technical or industrial applications. One goal is to identify methods able to control in a precise way the size of the deposited oxide particles and how they wet the metal substrate.<br/>
