Imaging Water Dissociation on TiO2(110)
Year: 2001
Type: article
Abstract: Scanning tunneling microscopy has been used to identify the adsorption site of ${\mathrm{H}}_{2}\mathrm{O}$ on ${\mathrm{TiO}}_{2}(110)\ensuremath{-}(1\ifmmode\times\else\texttimes\fi{}1)$ at 150 K, and to monitor the site of the dissociation products at 290 K. Water adsorbs onto the rows of fivefold coordinated Ti atoms at 150 K, dissociating by 290 K to form bridging but not terminal hydroxyls. This points to the involvement of bridging O vacancies in the dissociation pathway.
