摘要：

In situ Fourier transform infrared spectra (FTIRS) of species related to 'reduced' CO2 (r-CO2) adsorbates formed on columnar-structured Pt electrodes in aqueous 0.5 M HClO4, 0.5 M H2SO4 and 0.5 M H3PO4 at 25 degrees C are presented. From spectral, electrochemical and electrode topography data, the appearance of different types of complex adsorbates involving CO2, H-ads, multi, bridge-, and linearly bonded CO has been concluded. The influence of anions on the CO adsorbate adsorption band is tentatively interpreted through changes in the water-electrolyte structure caused by different types of anions.
