Abstract

Synchrotron-radiation based photoemission spectroscopy (SRPES) was used to examine the changes in the TiO₂ surface structures as a result of high-energy e-beam exposure (under atmospheric pressure). The influence of the e-beam pre-treatment on the structure of the post-deposited Pt films on TiO₂ was also investigated. High-energy e-beam treatment increased concentrations of OH species and C-O bonds on the surface. The interface reaction between Ti-oxide and Pt was reduced by the e-beam treatment. Consequently, different Pt film surface morphologies could be found on TiO₂ with and without e-beam treatment.
