Mechanistic studies on oxygen reduction reaction at the surface of carbonaceous materials applied for fuel cells

Development of structurally well-defined electrode surface materials for a high oxygen reduction reaction catalytic activity is a key approach for the construction of energetic fuel cells. A carbonaceous-based catalytic material gives a best offer for none-metallic approach designed cells. In this study, the oxygen reduction reaction activities of graphene oxide, graphene carbon-nitride and their mixing recipes. These materials are stable catalysts with high redox abilities and characterized as unique surface modifiers for fast electron transfer process. The electrochemical measurements for oxygen reduction reactions are monitored using the rotating disk electrode in both acidic and alkaline extremes for better understanding and interpretation.
