Kinetic Study of Formic Acid Oxidation on Highly Dispersed Carbon Supported Pd-TiO2 Electrocatalyst
The highly dispersed carbon supported Pd-TiO2 catalyst was prepared by a liquid phase reduction method with intermittent microwave irradiation. The kinetic parameters, such as the charge transfer parameter (alpha) and the apparent diffusion coefficient (D) of formic acid electrooxidation on a carbon supported Palladium Titanium dioxide (Pd-TiO2/C) electrode were obtained under the quasi steady-state conditions. The dependence on temperature of the formic oxidation at a Pd-TiO2/C electrode was also investigated and the activation energy (E-a) at different potentials was obtained.
