ABSTRACT
The elelctrocatalytic oxidation of glycerol on Pd electrode modified with Pt is investigated. The Pt-modified Pd electrodes with different Pt loadings are prepared by means of potentiostatic deposition of Pt on polycrystalline Pd electrodes. Scanning electron microscope (SEM) images show that the Pd substrate is partially covered by the Pt nanoparticles of different sizes. The Pt modification leads to an improvement in the catalytic activity of the Pd electrode for glycerol oxidation in alkaline solution, and the activity of the Pt-modified Pd electrodes has a close relation to the amount of the deposited Pt. In a wide range of the Pt loadings, the Pt-modified Pd electrodes show higher catalytic activity than Pd and Pt electrodes in terms of oxidation potential and peak current density.
