In a process for the preparation of a catalyst by vapor deposition of at least two different metal components to form a thin layer coating on a carrier with a thickness up to about 100 m10-5 to 1 mbar to form an amorphous metal alloy coating; and selectively reacting at least part of the metal compo
In a process for the preparation of a catalyst by vapor deposition of at least two different metal components to form a thin layer coating on a carrier with a thickness up to about 100 m10-5 to 1 mbar to form an amorphous metal alloy coating; and selectively reacting at least part of the metal component B with a reactive gas comprising at least one gas selected from the group consisting of oxygen, nitrogen and a hydrocarbon to form its oxide, nitride or carbide matrix, respectively, in which at least part of the metal component A is distributed in finely divided form, any remaining component A or unreacted component B being retained in the coating as the amorphous metal or an amorphous metal alloy.
