| Abstract: | Pt,Ru,and PtRu catalysts for methanol electrooxidation were electrochemically deposited and their catalytic activities and stability were studied.Both of the potentiodynamic and potentiostatic experimental results showed that the addition of Ru to Pt shifted the methanol oxidation peaks negatively with respect to Pt.Compared with Pt catalyst,PtRu catalyst shows a higher electrocatalytic activity for the electrocatalytic oxidation of methanol. |
