A catalytically active product, a method of producing such a product and a reactor comprising said product

A method of producing a catalytically active product, the method comprising:

• a) providing a substrate;
• b) depositing a thermite or thermate composition on the substrate, wherein the composition includes at least an oxide of a first metal and a powder of a second metal;
• c) heating the substrate with the composition to a temperature where the oxide of the first metal is reduced to the first metal in an exothermic reaction, wherein the second metal is oxidized to an oxide of the second metal, and thereby adhering the first metal to the substrate by heat from the reaction;
• d) removing the oxide of the second metal and thereby forming a layer of the first metal on the substrate, the layer having a rough surface;
• e) depositing a ceramic material on the rough surface of the first metal to form a ceramic layer thereon;
• and
• f) adding a catalytically active material to the ceramic layer.
