Preparation and Electro-Catalytic Performance of Pt-Ag/C as Electro-Reduction Catalysts for H2O2

Article Preview

Abstract:

Using impregnation-chemical reduction method, we prepared Pt/C and Pt-Ag/C nano-catalysts. Both of them are with the same platinum content. The composition of the two catalysts was analyzed by XRD technique. The electrochemical performance was studied by cyclic voltammetry and current-time curve. The results show that: the existence of Ag in the Pt-Ag/C catalyst makes Pt crystallinity decreased; compared with Pt/C, Pt-Ag/C has a higher reductive peak current. In addition, both catalysts show the excellent catalytic stability.
