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
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 characteristics of the ccrium(Iv) reduction have been examined at gold, glassy carbon and iridium rotating disk electrodes in 1 M sulphuric acid. Kinetic parameters have been evaluated from the reduction waves and are found to be independent of the electrode material. Cyclic voltammetric and rad
