Bimetallic copper - ruthenium - supported catalysts with a high sinter stability and a method for the production thereof.

摘要

Supported catalysts with a high sinter stability comprising one or more noble metal clusters - - - carbonyl compounds of the formula (1) of dollars a [ru φ a φ cu φ b φ l φ c φ (co) φ × φ] · n - · a · n + · dollars a wherein dollars a l for one or several, if applicable, different from each other, neutral or anionic ligands and dollars a (a) · n + · for one or more cations, which is able to compensate for the charge of the complex. Dollars a the compounds of the formula (1) are in the pores of a mesoporous carrier material arranged. Dollars a of the catalyst can be activated, in that the compounds of the formula (1) by means of a thermal, photolytic or chemical aftertreatment in the corresponding mono - or bimetallic noble metals m or mn, a form in their free. Dollars a the catalysts according to the invention are suitable in particular for the following reactions: hydrogenation, dehydrogenation, oxidation of organic compounds or peroxide - decomposition.
