Abstract:
A process for producing a ruthenium supported catalyst having a high sintering stability, which comprises one or both noble metal cluster carbonyl compounds of the formula:[Ru6C(CO)16]2âˆ’A2+or[H2Ru10(CO)25]2âˆ’A2+where A is one or more cations which balance the charge of the complex, and a mesoporous hydroxyl-containing support material, whereby the noble metal cluster carbonyl compounds are impregnated on the support material and located in the pores of the support material, said process comprises impregnating the mesoporous hydroxyl-containing support material with a solution comprising: (i) [Ru6C(CO)16]2âˆ’A2+; (ii) [H2Ru10(CO)25]2âˆ’A2+; or (iii) a combination of both [Ru6C(CO)16]2âˆ’A2+ and [H2Ru10(CO)25]2âˆ’A2+.
