Adsorption and oxidation of ethylene glyco(EG) on Pt(100) electrode were studied by in situ timeresolved FTIRS (TRFTIRS). The TRFTIR spectra recordedat 0.10 V illustrate that an IR band appears near 2050 cm?at t > 5 s, corresponding to linearly bonded CO formed indissociative adsorption of EG. The TRFTIR results haveconfirmed also that CO species are distributed uniformly onPt(100) surface. Another band appears near 2342 cm?1 at > 70 s, associating with IR absorption of CO2 produced inthe direct oxidation of EG. With the increase of electrodepotential, the direct oxidation of EG becomes gradually themain reaction. When the potential is above 0.40 V, the oxidation of EG occurs mainly via the reactive intermediates, *** containing –COOH determined by in situ TRFTIRS.
