英文摘要	the thin alumina film-supported metallic molybdenum model catalyst was prepared by thermal decomposition of mo(co)6, and co chemisorption on the catalyst was investigated in-situ by thermal desorption spectroscopy (tds) and x-ray photoelectron spectroscopy (xps). the results showed that a molybdenum-carbonyl-like species was formed on the alumina surface at low temperature by high coordination of co with the surface metallic molybdenum nanoparticles, indicating a reversible regeneration of molybdenum carbonyl on the alumina surface. co chemisorption on the model catalyst surface caused the mo 3d xps peak to shift toward higher binding energy. the formed molybdenum carbonyl species appeared at about 240 k in the tds. the supported metallic molybdenum nanoparticles were quite different from the bulk molybdenum in chemical properties, which indicated a prominent particle-size effect of the clusters.
