Abstract
Mo species on TiO2(110) surface were studied by means of Polarization Depen dent Total Reflection Fluorescence EXAFS. The structure and orientation of Mo species are strongly affected by the pretreatment conditions and impurit y. Mo dimer oriented to [1<1(1)over bar 0 >] direction and Mo chain structu re along [001] are present when they are prepared under oxidative condition s and reductive conditions, respectively. On the other hand, Mo tetrahedral monomer is formed when Na+ and K+ are present on the surface.
