Electrocatalytic systems based on platinum and tin oxides with different composition and microstructure characteristics were prepared via sequential electrochemical dispersion of tin and platinum electrodes under the action of an alternating pulsed current. The complex of physicochemical methods investigated the effect of electrolyte on the composition and structure obtained in the first stage of the synthesis of tin oxides.It is shown that the presence of tin oxide in a Pt-containing catalytic system generally has a promoting effect on the oxidation of ethanol on platinum. However, neither the composition nor the microstructure of the oxide affects the electrocatalytic properties of the Pt-containing catalyst.
