摘要：
The adsorption of SO2 on TiO2(110) surfaces at 100 K has been studied by means of the X-ray photoemission and ultra-violet photoemission spectroscopy, and photon stimulated desorption techniques using Synchrotron radiation. For a saturation dose at 100 K, the SO2 is molecularly adsorbed and a chemisorbed interface is formed by SO42- and SO32- species on the surface. Annealing of the adsorbed layer to room temperature leads to the formation of sulfur derived species. (C) 1997 Elsevier Science Ltd.
