摘要：
The reaction of oxygen reduction on the mercury electrode in the solution of the reversed micelles and in the presence of platinum and silver nanoparticles was studied. The data of inverse voltammetry show that in the presence of platinum nanoparticles the reaction can proceed via both two-electron and four-electron reaction mechanisms. In the case of silver nanoparticles it proceeds in accordance with the two-electron mechanism. Cumulative effect of catalytic action of platinum and silver nanoparticles on the molecular oxygen reduction was found.
