摘要：

Electrocatalytic performance of the Pt-TiOx/Ti electrode prepared with electrochemical reduction-oxidation method toward the oxidation of CO was studied. The effects of preparation conditions on the electrocatalytic oxidation of CO were also investigated. The experimental results show that the Pt-TiOx/Ti electrode has a high electrocatalytic activity, which Was manifested through the negative shift of the peak potential in the positive scanning of the cyclic voltammogram, and good stability for the electrocatalytic oxidation of CO. By means of XPS techniques, it is found that the Pt in the Pt-TiOx/Ti electrode is in a state of metal and the Ti is in a state of TiOx. The reason for the electrode to exhibit an excellent performance is attributed to the high dispersion between nanosized Pt and TiOx particles and the low adsorption ability of the CO on the electrode surface is due to the interaction between Pt and TiOx.
