Abstract

Supported catalysts having a high sintering stability and comprising one or more noble metal cluster carbonyl compounds of the formula (1)[HaMbNcLd(CO)x]n−An+and their use for the dehydrogenation, hydrogenation and oxidation of organic compounds whereM and Nare, independently of one another, one or more metalsselected from the group consisting of Pt, Rh, Ir, Os, Ru, Ag,Pd, Au, Ni, Fe, Co, Cu, Re, Mn;Lis one or more neutral or anionic ligands which may beidentical or different;(A)n+is one or more cations which balance the charge of thecomplex;ais an integer from 0 to 10, preferably from 0 to 6;bis an integer from 2 to 60;cis an integer from 0 to 30;dis an integer from 0 to 60;xis an integer from 1 to 120;nis the total charge of the complex which results from theindividual charges of the constituents and is greater than 0,wherein the compounds of the formula (1) are located in the pores of a mesoporous support material.
