| Abstract | 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/COxOy system was produced with various concentrations and proportions of the components. These samples are characterized by XRD, SEM, EDS, XPS and PCC (partial electrocatalytic curves) of CO oxidation and of NOx 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. |
