Abstract: The invention relates to methods for producing supported catalysts, comprising: providing a metal foam element A made of nickel; applying an aluminum-containing powder MP to metal foam element A, such that metal foam element AX is obtained; thermally treating metal foam element AX in order to form an alloy between metal foam element A and the aluminum-containing powder MP, such that metal foam element B is obtained; oxidatively treating metal foam element B, such that metal foam element C is obtained; and applying a catalytically active layer, comprising at least one carrier oxide and at least one catalytically active component, to at least one part of the surface of metal foam element C, such that a supported catalyst is obtained. The invention also relates to the supported catalysts obtained according to the method, and to the use thereof in chemical transformations.

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.

Abstract: The invention relates to a spectacle-type device (1) in which a full image can be depicted in a reliable manner by overlapping the first partial image (?3) and the second partial image (?4), wherein a correct full image can be perceived by the operator (2), and an action can be carried out with reliability when at least two items of image information coincide. The invention also relates to a method for depicting a full image and/or for carrying out an action using a spectacle-type device.
