When a metal is deposited on the surface of an oxide carrier, metal–support interactions may occur, the extent of which is strongly influenced by several parameters including the nature of both the metallic phase and the support, the morphology and size of metal particles, the oxidation state of the metal, as well as the nature and specific conditions under which the reaction is taking place. Such interactions give rise to electronic, geometric and bifunctional effects, which strongly influence the reactivity of reactant molecules in a number of applications. Ruthenium particles dispersed on oxide supports is a well known catalyst formulation for its capacity to undergo metal–support interactions, a parameter which could be utilized to influence the activity and selectivity of several catalytic reactions, including the CO and CO2 hydrogenation. In the present chapter, the general subject of metal–support interactions occurring over Ru based catalysts is discussed in detail with respect to (a) various physicochemical and operating parameters and (b) their effect in hydrogenating both CO and CO2.
