Photoemission studies of the reaction of benzene with TiO2(100)1×1 and 1×3

Abstract The adsorption and polymerisation of benzene on TiO 2 (100)1×1 and 1×3 surfaces has been investigated using AES, UPS and XPS. Benzene was found to adopt a tilted configuration on the 1×3 surface, and a near parallel orientation on the 1×1 surface at sub-monolayer coverages. Polymerisation is observed on benzene-dosed surfaces after X-ray irradiation. In addition, polymerisation or dissociation is also observed after exposure of the benzene overlayer to an electron beam.
