Fig. 1. (a) Example of a triangular potential waveform applied in the generation of a cyclic voltammogram. Representative CV responses for (b) a chemically reversible electron transfer (E mechanism), and (c) a chemically irreversible electron transfer in which the redox event is followed by a chemical reaction (EC mechanism). Two lines in (c) represent different rates of the following chemical reaction, where the dashed grey line has a rate constant of 0.1 s–1 and the solid red line a rate constant of 10 s–1 (with Ep/2 labelled for the latter). Arrows in figures demonstrate the direction of the scan, positive current represents oxidation.
