| Abstract: | The electrocatalytic Pt-Mo system was obtained by formation of platinum particles on the Mo surface under its contact with
PtC62− (PtCl42−) under the open circuit conditions. Cyclic voltammograms of the obtained Pt(Mo) electrodes feature well pronounced peaks
of hydrogen adsorption and desorption on Pt particles. Nonuniform platinum distribution across the electrode surface was found.
Pt(Mo) electrodes showed a higher specific activity in the reaction of methanol oxidation in the potential range of 0.35–0.45
V (RHE) as compared to Pt/Pt. |
