A method for the conversion of a surface layer of monolithic polymetallic carriers into highly active catalytic phases with a high specific surface area, which contain nanosized formations, was developed. An intermetallide layer was formed in the course of the high-temperature aluminum coating of the carrier surface; this layer was transformed into an active form by leaching and stabilization. A method was proposed for the enrichment of the aluminized layer in alloy additives. The microstructure of the intermetallide layer and the distribution of elements in it were studied with the use of chrome-nickel stainless steel gauze as an example. The physicochemical characteristics of the active phase were examined using a BET method, scanning electron microscopy, and X-ray diffraction analysis. The catalytic properties of the samples were studied in the processes of the deep oxidation of CO and propane and the hydrogenation of CO2.
