Oxyge electro-reduction in an acidic electrolyte on the gold nanoparticles–carbon carrier system

The synthesis of catalysts 20 Au/C with different degree of dispersion. These systems were investigated for activity in the oxygen electroreduction reaction with methods of the cyclic voltammograms and polarization curves. The increase of rate and depth of process (the number of electrons increases from 2 to 3.5) in the transition from compact to gold nanoparticles.
