Abstract

We have synthesized tin dioxide with a large specific surface area (122 m²/g), prepared platinum materials supported on it, and characterized them. The results demonstrate that Pt/SnO₂ + C composites can be used as catalysts for oxygen electroreduction. The stability of such a catalyst containing 50% carbon and 15 wt % Pt is better than that of commercially available Pt/C electrocatalyst containing 20% Pt.
