To obtain indications on the nature of the
transferred species, the F Δm
Δq
¼ F Δm=Δt
ΔQ=Δt function was calculated from
the EQCM data (Fig. 1A,B) which corresponds to the molar mass of the
species exchanged at the electrode/electrolyte interfaces at a given
scan rate. Fig. 1C shows that the estimated molar mass values are between
23 and 40 g·mol−1 in the potential range from -0.4 V to 0.05 V
vs Ag/AgCl.
