Quartz crystal microbalance study of the adsorption of ions onto gold from non-aqueous solvents

Abstract

This work investigates the adsorption of ions onto a gold electrode surface using an electrochemical quartz crystal microbalance. It was found that in anisole solutions adsorption of a monolayer of tetrafluoroborate anions or tetrabutylammonium cations occurred at different potentials, whereas in ethanol only tetrabutylammonium cations were adsorbed. The implications that this has upon electron-transfer processes are discussed.
