Cyclic voltammetry
= Cyclic voltammetry
<Cyclic voltammetry> sweeps an <electrode potential> forward and then reverses the sweep while recording <electric current>. The resulting current-potential curve probes <electron transfer> and chemical reactions coupled to it.
An oxidation peak followed by a reduction peak can indicate that an electrode-generated species survives long enough to react on the return sweep. Changing the scan rate changes the experimental timescale; loss of a return peak can therefore reveal a subsequent reaction, although transport and electrode kinetics must also be considered.
