| Abstract: | The potential-dependent adsorption behavior of water and ionic liquid was probed by surface-enhanced Raman spectroscopy (SERS) at the Ag electrode surface in the ionic liquids containing water with different concentrations.The configuration of water at the ionic liquid/electrode interface and the relationship between the potential of zero charge (pzc) and the molar fraction of water were deduced through the changes in the vibrational frequency of OH stretching mode.A small Stark effect value was determined ... |
