摘要：
The adsorption of aniline on the surface of a silver electrode in a neutral electrolyte aqueous solution was studied by FT-surface enhanced Raman scattering (SERS). A strongly enhanced Raman spectrum of aniline adsorbed on a silver surface was observed after roughening the silver electrode with an oxidation reduction cycle treatment. The SERS spectra revealed that aniline adsorbed on the electrode could be polymerized, even at a much less positive potential (+ 0.15 V vs. SCE) under laser-beam irradiation. The product on the electrode surface was also characterized by FT-IR microspectroscopy. As a result, it was indicated that polyaniline was formed only at the laser-irradiated site.
