Electro-Catalytic Performance of Different Pt/Ag Ratio on H₂O₂ Electro-Reduction for Direct NaBH₄-H₂O₂ Fuel Cell

Abstract:

In this paper the different proportional Pt/Ag on XC-72 carbon are studied to serve as the electro-catalysts of H₂O₂ in acid media. All catalysts are prepared by impregnation reduction method and characterized by XRD and TEM. The electrochemical performance tests are examined by cyclic voltammetry (CV) at 25°C and 30°C, respectively. The results suggest that the peak current density increases with increasing the Ag content in Pt-Ag/C. Attributed to the temperature factor, the electro-catalytic activity of all catalysts at 30°C is better than that of 25°C.
