Abstract

The adsorption kinetics of alcohols (methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol) was studied on monoatomic, two-dimensional SiO₂ single crystals (silicatene) using thermal desorption spectroscopy (TDS). Silicatene was grown on Mo(1 1 2) at ultra-high vacuum. In contrast to Mo, the alcohols physisorb molecularly on the hydrophobic SiO₂/Mo surface. Zero coverage binding energies vary from 46.5 to 65.5 kJ/mol and increase with molecular size. Silicatene was characterized by Auger electron spectroscopy (AES), low energy electron diffraction (LEED), and water TDS.
