Square-wave amplitude backward current

Fig. 2.15 SQWVforCriOs immersed into 0.10 M HCl shown (a) the net difference current between forward and backward pulses, and, (b) such currents and their sum. Potential scan initiated at +0.15 V in the positive direction. Potential step increment 4 mV square wave amplitude 25 mV frequency 5 Hz. Adapted from [149]...

The peak currents and potentials of the forward and backward components are listed in Table II.3.2. If the square-wave amplitude is not too small nEsw > 10 mV), the backward component indicates the reversibility of the electrode reaction. In the...
