Abstract

The solvent system adiponitrile (ADN) / tetraethylammonium tetrafluoroborate (TEA BF4) has been used to study the electrodeposition of various metals at both platinum and glassy carbon electrodes. Well-defined stripping peaks were found at each electrode for AgNO3 and Cu(NO3)2 systems, with slower electrodeposition kinetics at glassy carbon. For Hf(TfO)4 and Al(TfO)3, there is noticeable anodic activity after the initial reduction process; however, the stripping process is not as definite as in the silver and copper cases. Nucleation plots have been used to determine that copper(II) reduction at glassy carbon involves progressive nucleation at the peak reduction potential, while at platinum an instantaneous pathway is followed.
