Oxygen reduction in tetrafluoroethane-1,2-disulfonic acid
The kinetics of oxygen reduction on platinum in tetrafluoroethane-1,2-disulfonic acid (TFEDSA) and trifluoromethane sulfonic acid (TFMSA) have been studied with the rotating disk electrode technique at pH 1. The resulting Tafel plots coincide within the error of the experiment, indicating similar kinetics in the two electrolytes. The reaction order with respect to oxygen concentration was studied by varying the partial pressure of oxygen above the electrolyte. The rotation-independent currents at 0.90V vs. DHE were used to calculate a reaction order equal to one. A first-order analysis of the rotation-dependent currents was then used to extract kinetic currents at lower potentials. These kinetic currents also exhibited first-order dependence on oxygen concentration. 12 references, 7 figures.
