The effect of the SnO
2
 nanoparticles content on the structure and electrochemical behavior of Pt/(SnO
2
/C) catalysts containing about 20 wt% Pt was studied. In this case, SnO
2
/C nanostructured materials were obtained by tin electrodeposition on the carbon particles in suspension. It was found that the optimal combination of stability and activity in the oxygen electroreduction reaction is demonstrated by materials containing 25–30% wt. SnO
2
. A comparative assessment of the durability and activity of Pt/(SnO
2
/C) catalysts and a commercial Pt/C catalyst with 20% Pt-loading has been carried out.
