Surface fluorination of rutile (110) has been found to be effective in passivating the rutile (110) surface. This dissertation presents a simple method of TiO2(110) fluorination that involves the photoreaction of benzoate-terminated rutile (110) with O2 (g) in the presence of xenon difluoride XeF2 (g) as a fluorinating agent. The F-TiO2 (110) surfaces were characterized with scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS).enAttribution-NonCommercial-NoDerivatives 4.0 InternationalFluorinationPhotochemical reactionRutileScanning tunneling microscopy(STM)Surface passivationTiO2(110)dissertation or thesishttps://doi.org/10.7298/tbcw-2g02
