Abstract:

Work was directed toward the understanding of the mechanism of the oxygen reduction air electrode in nonaqueous media. The smooth platinumO2 saturated phenyltrimethyl ammonium hexafluorophosphate-nitrosodimethylamine system was studied extensively. The effect of water on the kinetics was also included. The overall process of oxygen reduction is a complex mechanism which includes two main reduction steps. The first reduction step includes an ECE mechanism with disproportionation as a side complication. The ECE mechanism consists of the reduction of oxygen to peroxide with superoxide as an intermediate. The second step is very irreversible and possibly is the reduction of peroxide to hydroxide which can only occur when protons are available. Water protons plays an important role in all of the mechanism. Accumulation of oxygen on the electrode and interaction between O2 and Pt was also studied. Author
