Sažetak

A method for electrochemical deposition of a two-component Ce1−xZrxO2 system on stainless steel substrate that is attractive from catalytic point of view is proposed. As reported in the literature, it is a promising carrier layer for the production of catalytic
converters for purification of exhaust gases containing NOx and CO. This system is modified by electrodeposition of a thin film of cobalt oxide over it. A series of samples of the Ce1−xZrxO2/СоxОy system was produced with various concentrations and proportions of the
components. These samples are characterized by XRD, SEM, EDS, XPS and РCС (partial electrocatalytic curves) of CO oxidation and of NОx reduction. Based on the obtained results, it has been concluded that the electrodeposited two-component Ce1−xZrxO2 system
is a solid solution with composition, structure, and physicochemical properties that make it suitable for use as active phase carrier for catalytic oxidation of CO and reduction of NOx.
