Studies on electrocatalytic performance of titanium oxide electrode modified with Pt toward the oxidation of methanol

Electrocatalytic performance of the Pr-TiOx/Ti electrode prepared with elec trochemical reduction-oxidation method toward the oxidation of methanol has been studied, The experimental results showed that the Pt-TiOx/Ti electrod e has a high electrocatalytic activity and good stability for the electroca talytic oxidation of methanol, By means of electrochemical, XPS, STM and in -situ FTIR techniques, it was found that one reason for the electrode to ex hibit an excellent performance is attributed to the high dispersion between nanosized Pt and TiOx particles, The low adsorption ability of the interme diate derived from methanol, such as linearly adsorbed CO species on the el ectrode surface due to the interaction between Pt and TiOx, also results in the excellent performance.
