Abstract

The present invention relates to a method for producing supported catalysts, comprising: providing a metal foam element A, which consists of metallic cobalt, an alloy of nickel and cobalt, or an arrangement of layers of nickel and cobalt, lying one over the other; applying an aluminum-containing powder MP to metal foam element A in order to obtain metal foam element AX; thermally treating metal foam element AX to achieve alloy formation between metal foam element A and aluminum-containing powder MP, in order to obtain metal foam element B; oxidatively treating metal foam element B, in order to obtain metal foam element C; and applying a catalytically active layer, comprising at least one support oxide and at least one catalytically active component, to at least part of the surface of metal foam element C, in order to obtain a supported catalyst. The present invention further relates to the supported catalysts that can be obtained using the method and to the use of said supported catalysts in chemical transformations.
