Blocking interstitials : The strong effect of ambient O 2 on the surface chemistry of TiO 2 (110) is demonstrated for the first time by using molecular imaging. Scanning tunneling microscopy experiments show that O 2 reverses and inhibits the formation of a diolate coupling intermediate, whereas H 2 O does not (see figure). The strong affinity of O 2 for titanium interstitials, which are necessary for coupling, accounts for these effects.
