Silver electrodeposition from water-acetonitrile mixedsolvents in the presence of tetrabutylammonium perchlorate Part II-A SERS study of acetonitrile reactivity and tetrabutylammonium adsorption

摘要

In this paper, surface-enhanced Raman spec-troscopy has been used to investigate the electrode/electrolyte interface during Ag electrodeposition fromwater–acetonitrile mixed solvents. The reactivity ofacetonitrile during Ag electrodeposition has been moni-tored, promoted by the electrocatalytic activity of silverclusters electrodeposited onto the electrode surface. Theeffect of the addition of tetrabutylammonium cations tothe mixed solvents has been investigated and itsadsorption and tilting on the silver surface has beenfollowed as a function .of the cathodic overpotential.
