　　In this study,the composite catalysts Ag@Pt/MWCNTs-PMo12-nVn(n=1,2,3)catalysts were prepared by acidification-extraction method and chemical impregnation method.Morphology and surface composition analysis showed that we have successfully prepared the PMo12-nVn(n=1,2,3)and the composite catalyst.The electrochemical test results showed that the activity and stability of the composite catalyst were obviously improved.When the loading of PMo10V2 is 20%,the activity of the composite catalyst is the best.The electrochemical active surface area(97.86 m2·g-1)was 86%higher than that of commercial Pt/C catalyst(52.63 m2·g-1).
