TL;DR: In this article, confocal microprobe Raman spectroscopy and a unique electrochemical pretreatment procedure for the Pt surface were used to extend the detailed surface Raman studies, for the first time, to bare Pt electrodes in a wide potential region (e.g. −1.0 to +1.4 V vs SCE) and to more general adsorbates such as SCN and CO having small Raman scattering cross sections.
Abstract: By using confocal microprobe Raman spectroscopy and a unique electrochemical pretreatment procedure for the Pt surface, we are able to extend the detailed surface Raman studies, for the first time, to bare Pt electrodes in a wide potential region (e.g. −1.0 to +1.4 V vs SCE) and to more general adsorbates such as SCN- and CO having small Raman scattering cross sections. Taking advantage of being capable of observing the adsorbate−metal vibrational bands in the low-frequency region over IR and SFG techniques, the surface Raman spectroscopy has demonstrated the virtues of yielding detailed information on the surface bonding affected by surface coverage, coadsorbate, electrolyte ions, and electrode potential. The potential-dependent Raman spectra of SCN- reveal that the N-bound adsorbate is favored at the more negative potentials. The orientation conversion to the S-bound species occurs in the more positive region, depending on the SCN- concentration. In a solution of 10-5 M NaSCN and 0.1 M NaClO4, a new C−N...
