Potential Window of Pt, Hg, Carbon electrodes in aqueous solution

The figure below shows the appropriate materials of the electrodes to research at some potential range. To analyze the redox activity of a substance dissolved in a kind of aqueous electrolyte with certain pH, it is indispensable to consider about electrode's hydrogen over, oxygen over voltage and dissolution potential.
