摘要：

Synchrotron-radiation-induced photoelectron spectroscopy (SRPES) has been used to investigate the reaction of NO2 over vanadia thin films at different coverages on TiO2(110)-1 x 1. The stoichiometry and structure of the vanadia films are controlled to be VO2, rutile structured, using a previously published non-dioxygen-ambient method of synthesis in UHV. The reactivity of these VO2 films towards NO2 varies with their coverages. The results are interpreted with regard to the surface structure and stoichiometry. (C) 2002 Elsevier Science B.V.
