Abstract
The interaction of n-octanohydroxamate with a copper electrode was investigated using cyclic voltammetry, contact angles, surface-enhanced Raman scattering, neutron reflectometry and X-ray reflectometry. The data demonstrated that hydroxamate specifically adsorbed at underpotentials in the keto tautomeric form, but the layer was hydrophilic and contained >50% water. In the CuI stability region the hydroxamate moiety took on the enol tautomeric form but the interface remained hydrated. Co-adsorption of electrolyte species was observed at underpotentials. The adsorbed hydroxamate at the surface did not prevent the formation of oxide in the CuI stability region. A hydrophobic non-passivating multilayer of copper n-octanohydroximate formed in the CuII stability region. © 2014, The Electrochemical Society.
