Abstract

A method for producing a shell catalyst which comprises, in the outer shell, one or more of the following metals: Pd, Pt, Ag and Au. Also the use of the shell catalyst produced using the method according to the invention for the production of vinyl acetate monomer, in the hydrogenation of hydrocarbons, in particular the selective hydrogenation of polyunsaturated hydrocarbon compounds, or in the oxidation of alcohols to ketones/aldehydes/carboxylic acids.
