Dear Piyush

Your question is not quite clear. However, the oxygen evolution reaction has to do with the oxygen over voltage, the voltage at which the oxygen evolves during the anodic polarization reaction of a sample in a solution. This occurs during the DC anodic polarization of the sample in the particular solution in a potential range between -400 to 1600 mV, with respect to the open circuit potential of the sample in the solution.

In contrast, the AC anodic polarization of a sample in a solution under a potentiostat condition ,i.e., +/- 5mV, through a frequency range from 0.01 to 100000 Hz might not lead to oxygen over voltage. In other words,the oxygen evolution reaction might not be observed in order to calculate the corresponding frequency during the AC anodic polarization of the sample in the solution.

Thank you sir, but i am searching for electrochemical oxygen evolution reaction at the electrode surface in acidic or basic medium.

I want to calculate the turnover frequency using electrochemical method.
