Preliminary experiments using platinum electrodes established that a Pt-Au weld immersed in the electrolyte had no effect on open-circuit and Tafel behavior of platinum.
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
The kinetics and mechanism of O2 reduction on an Ru electrode in acid electrolytes have been measured by using a disc-ring method. The reaction proceeds through a "parallel" mechanism with the exchange of approximately four electrons. It shows a pronounced dependence on the oxidation state of the Ru
The kinetics of oxygen reduction at Pt in trifluoromethanesulphonic acid (TFMSA) (0.05-6.0 M) and in 1.0 M TFMSA with addition of small concentrations of phosphoric acid (0.003-0.1 M) was investigated using the rrde technique. In TFMSA, the oxygen reduction current on the oxide-covered Pt was found
