The higher thermal resistance and the mechanical strength of the catalytic element carriers produced on metal substrates contribute to the further interest of the automotive industry on them despite that they show a smaller development of the surface compared to the ceramic carriers. The present work was focused on testing the catalytic properties of oxide films obtained as a result of the high-temperature oxidation of 0H18J5 steel foil under mixture of oxygen and argon which were coated with platinum by reactive dc magnetron sputtering. Hybrid coatings obtained by the oxidation of metal foil prior coated with aluminum nanofilms and then with platinum and the aluminum- platinum composites were also tested. The catalytic activity of the obtained coatings was tested by the pulse method in 2-methylol-3-butyn-2-ol decomposition reaction and the flow method in the process of cyclohexane oxidation. A catalytic test enabling the parameters of cyclohexane oxidation (temperature, time of reaction, cyclohexane concentration in zone of reaction) using the air to be controlled was developed for this flow method. The tests being carried out revealed an influence of different configuration of oxide films and platinum on their catalytic properties. Moreover, a high activity of alumina-Pt systems in the process of cyclohexane reheating with the air was confirmed.
