Metal foils play more and more important part in production of catalytic converters for exhaust and industrial gas. The deposition of the active phase on the foil surface makes it possible to create the optimum conditions for the catalytic process and obtain the high-duty converters resistant to vibrations and thermal shock. The work was focused on the new thin-film technique designed for depositing the laminar and hybrid oxide systems obtained as a result of the high-temperature oxidation of the foil made of OH18J5 heat resisting steel, using a mixed oxygen-argon atmosphere with equal volume fractions, and then they were coated with Al2O3 nano-films by sputtering the alfa Al2O3 monolithic target with the aid of an r.f magnetron. Both the oxide layers without coating and the layers coated with Al2O3 nano-films were deposited with Pt coats by sputtering the metal target from a d.c magnetron. The thickness of each sputtered Al2O3 and Pt film did not exceed 25 nm. The catalytic activity of the obtained coatings and their acidic-basic properties within the range of b temperatures 523-673 K were determined on the basis of a 2-methylol-3-butyn-2-ol decomposition reactio
