Ah&act-The cathodic V log i curves for On reduction on oxide-free Pt electrodes were determined in oxygen-saturated purhied acid (HClO,, pH l-3) and alkaline (NaOH, pH 13) solutions. It was found that aV/aiogi = -2.3RTlF, .ayalOgp,, = -23RTlF and W/a pH = -100 mV. Coverage of electrodes by oxy gama
The steady-state reduction ofoxygen in O,-saturated 2 N H,SO, solution was obtalned at constant current on the front side of a Pt fo11 diaphragm before and after strong anodization of the back side. Strong anodization converts the Pt to a Pt-0 alloy. In all cases, the overvoltage for O2 reduction wa
