Electrochemical kinetics of gold electrodes in SCN<sup>−</sup>/dimethylsulfoxide solutions

The electrochemical behaviour of the Au/SCN<sup>−</sup> (DMSO) interface is studied at 25°C≤T≤65°C, by means of the triangular potential sweep technique and the RDE. Within a relatively limited potential range the main electrode process is: 3 SCN<sup>−</sup>=(SCN)<sub>3...

Descripción
Sumario:The electrochemical behaviour of the Au/SCN<sup>−</sup> (DMSO) interface is studied at 25°C≤T≤65°C, by means of the triangular potential sweep technique and the RDE. Within a relatively limited potential range the main electrode process is: 3 SCN<sup>−</sup>=(SCN)<sub>3</sub><sup>−</sup>+2e The kinetics of this reaction involves a mixed control. At higher potentials the electrodissolution of the base metal takes place. Side reactions occurring there make the overall process rather complex. The electrochemical behaviours of the Au/SCN<sup>−</sup> (DMSO) and Au/SCN<sup>−</sup> (ACN) are compared.
