Popis | The adsorption of naphthalene, tetraline and biphenyl at Pt(111), roughened Pt(111) and polycrystalline Pt electrodes was studied using differential mass spectrometry (DEMS). From the amount of carbon dioxide evolved during oxidation of the adsorbate layers, coverages were estimated to be around 0.2 nmol sqcm for all three molecules. Less than half of adsorbate formed from naphthalene or tetraline can be desorbed as main product, the rest of adsorbate undergoes to hydrogenation. |
