✦ Synopsis

The adsorption of SO, on TiO,f I IO) 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 Synchrorron radiation. For a saturation dose at 100 K, the SO, is molecularly adsorbed and a chemisorbed interface is formed by SO<-and SOS-species on the surface. Annealing of the adsorbed layer to room temperature leads to the formation of sulfur derived species.

The activation of the 110 TiO rutile surface by deposition of alkali 2 metal atoms has been the subject of some recent experimental studies. These results indicate a reduction of the surface when sodium atoms are deposited on it. In the present work, this process has been studied by means of ab init
