Multiple adsorbate interactions between reduced CO<sub>2</sub> adsorbates and either allyl alcohol or propargyl alcohol residues on platinum in 0.5 M sulphuric acid

The interaction of propargyl alcohol and allyl alcohol with a platinum (Pt) electrode modified by the presence of reduced CO<sub>2</sub> adsorbates (r-CO<sub>2</sub>) is studied through voltammetry and potentiostatic current transients by using a flow cell technique. The inte...

description The interaction of propargyl alcohol and allyl alcohol with a platinum (Pt) electrode modified by the presence of reduced CO<sub>2</sub> adsorbates (r-CO<sub>2</sub>) is studied through voltammetry and potentiostatic current transients by using a flow cell technique. The interaction between each alcohol and r-CO<sub>2</sub> is promoted at three constant potentials corresponding to different degrees of Pt surface coverage by H-atoms. For both alcohols the anodic stripping peaks and the charge balance are interpreted in terms of the formation of composed adsorbates. Based upon the probable r-CO<sub>2</sub> structure and H-bonding interactions between r-CO<sub>2</sub> and the alcohol molecules or their adsorbed residues, average alcohol residues/r-CO<sub>2</sub> molecular ratios are estimated.
