The present invention relates to a process for the production of a shell catalyst which comprises a catalyst support shaped body with an outer shell in which metallic Pd and/or Au is contained. In order to provide a process by means of which shell catalysts can be obtained, in the outer shell of which relatively high metallic Pd and/or Au contents are contained, a process is proposed comprising the steps of a) providing a porous catalyst support shaped body; b) providing a first solution in which a Pd and/or an Au precursor compound is contained; c) providing a second solution in which a Pd and/or a Au precursor compound is contained, wherein the first solution brings about a precipitation of the noble-metal component(s) of the second solution and the second solution a precipitation of the noble-metal component(s) of the first solution; d) loading the catalyst support shaped body with the first and with the second solution; e) converting the noble-metal component(s) precipitated on the catalyst support body into the metal form.
