The electrochemical reduction of oxygen on thin Pd films with a nominal thickness of 0.25-10 nm on polycrystalline Au substrate (Pd/Au) was studied. The Pd films were prepared by electron beam evaporation and oxygen reduction was studied in 0.1 M HClO 4 and 0.05 M H 2 SO 4 solutions using the rotati
In basic media pyruvate anion oxidizes on a polycrystalline gold electrode. The number of electrons involved is two per pyruvate molecule, and the final products are acetate and carbonate. The oxidation is strongly inhibited by the appearance of gold oxides, and a self-inhibition process takes place
