Voltammetric measurements by cyclic voltammetry (CV)
The modified electrode was placed into a voltammetric cell. The
measurement was carried out in the background electrolyte, in
acetonitrile (propionitrile), with different scan rates (0.01–0.1
V s1). The conditions were as follows: Ebegin = 1.5 V, Eend = 1.5 V
and Estep = 0.005 V.
