In alkaline solutions, electrochemistry of oxygen is not as greatly affected by purification of the solutions as in acidic media [45]. Since the earlier RRDE experiments, it has been shown that H2O2 is the main product of the reduction in the activation domain but is not detected anymore at lower potentials, when the electrode reaction is limited by mass transport [59, 64, 65]. The existence of two potential regions for ORR in alkaline media is also illustrated by the Tafel plots, as those reported in Fig. 6 [66]. The existence of two...

Cathodic reduction of oxygen is the most convenient method of production of the superoxide radical-anion,. The properties of this important species have been well reviewed and key references to the extensive work on the electrochemistry of oxygen are contained therein. Of immediate significance is the large cathodic shift in E° for the 0 /0 couple which accompanies a change from aqueous to aprotic solvent (e.g. DMF, DMSO, and MeCN) this is interpreted in terms of relatively weak solvation in aprotic media which enhances the nucleophilicity of the superoxide anion. However, in the presence of acids the chemistry of superoxide is dominated by the disproportionation shown in equation 1.
