英文摘要A thin and homogeneous alumina film was prepared by deposition and oxidation of aluminum on a refractory Re(0001) substrate under ultrahigh vacuum conditions. X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS) and high-resolution electron-energy-loss spectroscopy (HREELS) demonstrate that the oxide film is long-range ordered, essentially stoichiometric and free from surface hydroxyl groups. The chemisorption and thermal decomposition of MO(CO)(6) on the Al2O3 film were investigated by means of XPS and UPS. MO(CO)(6) adsorbs molecularly on the oxide film at 100 K; however, thermal decomposition of the adsorbate occurs upon annealing at high temperatures. Consequently the metallic molybdenum clusters are deposited on the thin alumina film via complete decarbonylation of MO(CO)(6). (c) 2006 Elsevier B.V. All rights reserved.
