1. Thin-film voltammetry

Thin-film voltammetry appeared in 1961. Its principle and applications have given rise to several successive developments . Here we will only discuss a few aspects of its implementation.

The principle of this technique consists of isolating, on the surface of the working electrode, a very small amount of the electroactive species that will participate fully in the electrochemical reaction. Unlike conventional methods, where electrochemical transformations do not significantly alter the composition...
