The method of producing a thin layer of catalytic material on substrates of electrically conductive material, especially on metal grids used as a filling of structural reactors for removing harmful volatile chemical compounds from waste gases, consists in the fact that the substrate on which the layer is to be formed is first processed initial, causing the surface to develop, after which the substrate is placed on a “hot" electrode or as one of the electrodes, preferably as a “hot" electrode, a low-pressure plasma reactor and exposed to plasma generated by glow discharge at acoustic frequency or radio frequency, using as gas a working mixture of inert gas and a gaseous oxygen carrier, and as a precursor an organometallic transition metal compound or a mixture of organometallic transition metal compounds in the form of vapor. The substrate, together with the applied catalytic layer, is optionally subjected to soaking in the presence of air.
