Identical to the oxidative scan direction, the samples exhibit an intrinsic conductivity at the OCP, which continuously increases with increasing reductive potential. Beyond -2.08 V, similar shifts of the onsets occur as in Fig. in conjunction with a notable overall increase in the conductivity by approximately doubling it. Analogous to the course of the differential capacitance, a shoulder arises at approx. -2 V vs. Fc/Fc + . During the back scans (dotted lines), the conductivity is smaller and no longer mirrors the forward scan. The accumulated charge (Fig. ) also reflects this analysis. For reductive potentials below |-2.08 V|, the forward and back scans are identical, while a hysteresis occurs for more extended reductive scan windows.
