Adsorption and electrochemical reaction of graphen oxide (GO) at an Au surface was studied by surface enhanced infrared absorption spectroscopy (SEIRAS). GO film on the Au electrode is formed within 1 min. in 0.4 mg ml^-1 of GO aqueous dispersion solution. Also, it was shown that, by applying −1.0 V vs Ag/AgCl, the epoxy group of GO was reduced in 0.4 mg ml^-1 of GO and 0.1 M NaClO₄ solution, and the reaction was irreversible within the potential region under the experimental conditions studied here.
