A new hydrogenation catalyst is formed by thermolysis of the anionic carbonyl cluster [Ag3Ru10C2(CO)28Cl]2− anchored to the mesoporous silicate MCM-41. The cluster was isolated and characterized in MCM-41 both before and after thermal treatment. The picture on the right shows a model, based in particular on EXAFS analysis, of the active bimetallic particle. The distribution of the Ag/Ru particles in the MCM-41 cavities was determined by electron microscopy.
