The adsorption of carbon dioxide, a Lewis acid, and trimethylamine, a Lewis base on the clean and partially oxidized molybdenum (100) crystal face was followed by LEED and Auger electron spectroscopy. CO2 adsorbs dissociatively on clean Mo(100) but does not adsorb on the oxidized surface. N(CH3)3 adsorbs dissociatively on the clean Mo(100) surface but chemisorbs in molecular form on the oxidized surface. The difference in adsorption behavior is attributed to an alteration in the surface electronic structure caused by charge transfer from the metal atoms to the oxygen.
