Supported bimetallic copper-rhodium catalysts with high sintering stability and process for their preparation

摘要

Supported catalysts with a high sintering stability contain ruthenium-copper-carbonyl cluster compounds inside the pores of a mesoporous support material. Supported catalysts with a high sintering stability, containing precious metal cluster carbonyl compound(s) of formula (I) inside the pores of a mesoporous support material: L = optionally different neutral or anionic ligand(s); An+ = one or more cations to balance the charge on the complex; a = 1-147; b = 1-55; c = 0-200; x = 1-120; n = total charge on the complex = sum of charges on individual components = greater than 0. An Independent claim is also included for a process for the production of these catalysts by impregnating a hydroxyl group-containing support material with compounds of formula (I).
