Results and Discussion
Figure 3.4. a) EIS and b) CV of a clean 2 mm diameter gold electrode performed in
K3[Fe(CN)6]/K3[Fe(CN)6] (5 mM each) in 10 mM phosphate buffer (PB), 20 mM K2SO4.
EIS measurements were performed by applying a DC potential of 220 mV superimposed
by a 5 mV AC perturbation. The frequency range was scanned from 30 kHz to 10 mHz.
CV was performed at 100 mV/s scan rate.
