Studies of the Structure and Electrocatalytic Reduction of Oxygen on Modified Electrode Surfaces
Finally, the mechanism of the electroreduction of oxygen on Au surfaces in basic media is examined using SERS and density functional theory calculations. The spectroscopy reveals superoxide species as a reduction intermediate, while no peroxide is detected. The spectroscopy also shows the presence …
