| dc.description | The reactivity of isopropanol on polycrystalline Pt in acid solutions was investigated using in-situ Fourier transform IR spectroscopy (FTIRS) and on-line differential electrochemical mass spectrometry (DEMS). The electro-oxidation products are acetone and CO<sub>2</sub>; the former is observed when isopropanol is present in the bulk of the solution, and the latter is produced from strongly adsorbed species. Both bulk and adsorbed isopropanol electro-reduction yield propane. H-D exchange is observed during propane formation when the reaction takes place in a D<sub>2</sub>O + DCIO<sub>4</sub> solution. This observation suggests the formation of adsorbates bonded to the surface through the C ∝ atom of the isopropanol molecule. FTIR spectra of adsorbed species show the presence of -CH<sub>3</sub> and -COH groups. The most probable adsorbate structures are (CH<sub>3</sub>-C-CH<sub>3</sub>)Pt, (CH<sub>3</sub>-CH-CH<sub>3</sub>)Pt and (CH<sub>3</sub>-COH-CH<sub>3</sub>)Pt, presumably accompanied by (CH<sub>3</sub>-CO-CH<sub>3</sub>)Pt. | |
