Abstract
The potential-dependent behavior of silicotungstate, alpha-SiW 12O404-, on copper, silver, and gold electrode surfaces was investigated using SERS and PM-IRRAS. The results show that silicotungstate interacts with Cu surfaces. This interaction is shown to be potential-dependent; alpha-SiW12O404- associates with the Cu surface to a greater extent as the potential is stepped negatively. As the potential is stepped back positively, the alpha-SiW 12O404- still interacts with the surface.
