The mechanism of the oxygen evolution on RuO2 and Ru0.9Ni0.1O2-delta anodes was studied in 0.1 M HClO4 using (18)labeling combined with differential electrochemical mass spectrometry (DEMS). It was shown that the mechanism of the oxygen evolution is potential sensitive. At potentials negative to 1.12 V vs. SCE all the evolved oxygen originates from the electrolyte solution. At higher potentials an additional mechanism involving an exchange of the oxygen between electrolyte and electrocatalyst starts to apply. The extent of this oxygen exchange mechanism reflects the chemical composition of the electrocatalyst and is significantly higher at Ru0.9Ni0.1O2-delta electrodes. (C) 2009 Elsevier B.V.
