Abstract
The effect of the amount of gold used as the dopant of PtCu nanoparticles on the structure of PtCuAu/Cu catalysts and their activity in the reactions of oxygen reduction and methanol electrooxidation is studied. The PtCuAu/C materials containing from 3 to 20% of gold are prepared by galvanic displacement of copper atoms by gold atoms on the surface of already prepared PtCu nanoparticles. The addition of 5 at % Au to the composition of nanoparticles doubles their activity in the methanol oxidation and increases their activity in the oxygen reduction by a factor of 1.7 as compared with the commercial Pt/C material JM40. This study confirms that multicomponent platinum-containing nanoparticles supported by a highly disperse carbon material and having gold atoms deposited on their surface show promise as the efficient catalysts for the methanol fuel cells. In contrast, the materials containing 10 at % Au and more are characterized by the presence of gold nanoparticles on the carbon support surface and exhibit the lower catalytic activity as compared with those containing less amounts of gold.
