FIELD: chemistry.

SUBSTANCE: invention relates to general or special catalysis, particularly to methods of producing catalysts for oxidising carbon oxide and hydrocarbons and can be used in systems for reducing toxicity of exhaust gases from various technological processes, where gas released into the atmosphere contains harmful organic substances and carbon oxide. Described is a method of producing a catalytic composite coating, involving obtaining a catalytically active layer on a metal carrier via plasma sputtering of a powdered composition onto a metal carrier. An adhesion layer is deposited by sputtering a powdered composition containing the following in wt %: aluminium 3-5, aluminium hydroxide - the rest; a porous catalyst layer is deposited by sputtering a powdered composition containing the following in wt %: aluminium 3-5, chromium oxide 2-5, tungsten oxide 0.8-1.2, oxides of cerium, lanthanum, neodymium in total of 1.8-2.2, copper oxide 2-3, aluminium oxide - the rest; an activator layer is then deposited via a ion-plasma technique using two evaporators, where the said layer contains the following in wt %: copper oxide 27-34, chromium oxide 66-73.

EFFECT: higher strength of adhesion of the catalyst layer to the metal carrier, lower ignition temperature while retaining high catalytic activity.
