Abstract:

Although surface-enhanced Raman spectroscopy (SERS) is probably one of the most sensitive surface spectroscopic techniques, most of the previously electrochemical SERS studies have been carried out in steady state. Recently, much attention has been attracted to combine time-dependent SERS with electrochemical transient techniques to investigate the electrode/solution interfacial dynamics at molecular level[1,2]. Our previous studies indicate that thiourea (TU) can coadsorb with ClO4- at Au electrodes in steady state. In the present work, time-dependent SERS has been used to study the structural change with the potential step for the coadsorption system.
